Would only recommend that you use newer version that is less behind, if you don't have particular reasons to use old version.

there is no reason to use old version.actually i am new one to linux. currently i am training myself on red hat 6 but i check today from different forums that there's a lot of difference in redhat 6 and redhat 7 versions according to commands also. on this point i am confuse which version i have to continue for practice to train myself.

rhel 6.7 and 7.1

keep in mind that RHEL7 is VERY VERY different than RHEL6

SystemD VS. SystemV

Go for CentOS 7. Even if you manage to get your hands on RHEL 7 ISO and install RHEL 7, you'd be unable to install any updates or additional applications without subscription for RH support. With CentOS, you'll get it all minus the RH branding.
What resources do you plan on using for your RH cert preparation?

Actually I'd say go for CentOS 6 first, then dip your toes in 7. 6 is the more "traditional" one and as such you'd have less problems understanding the differences between 6 and 7. Learning 7 first and then seeing 6 is awkward, chronologically incorrect plus it's not like you wouldn't encounter any 5 or 6 in Real Life, so.

I'd agree with starting on CentOS 6. Red Hat is supported for 10 years and businesses do not like changing things until they have to, so you'll find plenty of servers still running versions 5 and 6. Both are similar, so learning 6 prepares you for 5 as well. Apart from the difference in start up mentioned by John, most of what you learn will also work for 7. Once you feel confident, you can move on to version 7 and the mysteries of systemd.
