I've been using Mint 15 Cinnamon and other users are also facing the same issues:
Hibernation data is lost because of hang while shutting down: Forum, so many "same here"'s
Freezing issue: bugs.launchpad
Sometimes no sound after booting and have to restart: bugs.launchpad
I've faced some other bugs too. "Many Minor Glitches Make Mint 15 More Work Than It's Worth" - Linux Insider Review

Don't need help in this as my applications' requirements are few and basic, thanks
My experience with different distros mentioned on this thread:
Kubuntu LTS 12.04.3 (I prefer KDE over Unity)
Installer crashed when I was choosing partitions. ( Core i3 Ivy Bridge 2.5Ghz, 6GB RAM )
openSUSE 13.1 KDE-Live
Installer gave error that it's not able to unmount a partition. openSUSE had automatically mounted the first swap partition. It wouldn't require swap with 6GB RAM. But it gave me option to continue the installation. It didn't allow me to have a single character as username; this is not an account creation on a website. After the first system start, I hibernated it but then on the boot it hanged. Holding down the power button of laptop didn't shut it and had to take out the battery.
Salix 14.0.1 Xfce
The same hibernation bug as openSUSE. As the default LILO installed with Salix wasn't listing other operating-systems, the next thing I tried after testing hibernation, was using Salix's pre-installed GUI application for configuring LILO, but encountered another bug.
The hibernation bug affected only the first hibernation in both openSUSE and Salix, subsequent hibernations worked in both.
Debian 7.1 net-installation
After the installation was complete, it didn't allow me to login using the password I had set. I found out from forums that it doesn't allow logging in as root into desktop-environment. I had created only root account and during installation it didn't give me any warning that I won't be able to login into desktop-environment. Salix did give me this warning so I created another account during Salix installation.
Debian 7.2 KDE-live
Problem with hardware support: Internet was slow - I tried the internet on two different days switching between Mint, didn't detect bluetooth and detected touchpad as normal mouse so no edge scrolling. I don't blame Debian for these. I downloaded Chrome installation from Chrome's website, opening the ".deb", Debian gave error: "Your current backend does not support installing files". Its KDE didn't have a feature which I want, that must be due to it using an older version of KDE.
I didn't try it after this thread because I've already tried it as the first Linux distro I've installed. During the graphical installation, after I had tick-marked on what all to install, it gave an error that a dependency is not being satisfied; I was expecting that by marking something during installation, all its dependencies should automatically get marked. Then it neither gave me a button "include all dependencies", nor "whatever package is causing trouble, uncheck that package". When setting password, it first gave error that length is too short, then after I increased the length, it gave error that the password is too simple. Logging into the desktop-environment, the bug reporter tool said that there's a problem. Just opening add/remove programs gave another error, when I searched it on net, some other CentOS/Fedora users were also getting the same error. Then I wanted to do something simple (I don't remember what) and I had to spend a lot of time to do that. After my experience with CentOS, I shifted to Mint.
Didn't try Scientific as already tried CentOS and don't like some things about Red Hat.
PC-BSD 9-Stable USB Live
When I booted from USB installation, the first question it asked me was that whether I want to boot into single user or multi-user. I didn't know what that means so I let it do the default action. Next question it asked that do I want to expand the file system. I didn't know this also so I let it make the default choice. Then it gave some output and stopped, there was no question on the screen, I hit 'enter' key and it rebooted into blank screen.
The only Linux distro which let me enter the desktop-environment as root user and that too when I hadn't set any password for root. But it would need time to be completely set up, especially when it didn't detect bluetooth and detected touchpad as normal mouse. (I don't blame it for bluetooth and touchpad)
I'm not asking for further advice; I shared as someone else reaching this thread because of having the same question may want to know. The suggestions you guys have given me are correct; I asked for most reliable Linux distro for desktop usage, and the ones you've suggested are actually the most reliable; thanks again
