At the OP, I think what the moderator means is that while a descriptive title is good, unless you say something like, "The title is in the question," someone just scanning your post won't even notice it. See
especially if you're planning to go into the IT field.
I went through the cert issue about 10 years ago--at the time, MCSE seemed the easiest (I was in a different situation though--I was in my 40's and had decided to make a career change), and at the time, there seemed, in my area anyway, to be more jobs available in that field. What I've found since then, however is that while certs might get the HR people to look, most people care far more about what you know. The RHCE is probably the only one that will impress the tech people who will (or should at least), have the final say on hiring.
(This US Tri-state area centric, but apparently true through the rest of the US as well, though please do not take my statements as fact, it's just my impression. US Tri-state means NY, NJ, and CT, three states in the US Northeast.)
That being said, if possible, choose the one that you like the most. If what keeps you up late solving problems is Windows Active Directory, choose the MCSE. If playing with routers is what you love, and the one that keeps you up late at night, solving issues, then go for the CCNA. (The follow up Cisco certs, especially CCIE, also impress potential employers.) If it's Linux that really moves, then go for the RHCE.
I don't know your circumstances, and you may not have that luxury. Also, things have changed since I did this, but at the time, the MCSE was about 12 different tests, the CCNA one test, and the RHCE was also one test, but a very hard one, and also extremely expensive. (In NYC at the time, the MS and Cisco tests were $100 USD each, while the RH test wasn't even offered in NYC, and cost a couple of thousand dollars).
