It really depends on what type of plugins you're talking about.
The ones that highlight syntax errors in python, or js, or that spit out compilation errors for C are a must, and one of the most important features for me.
The plugins that take hours to configure, and let you press on key instead of three for some infrequent action: yes, avoid them. No matter how fancy they look, and how well someone tries to sell it to you.
CtrlP is also a must for me. Instantly open any file, even if I vaguely recall it's name. And no configuration necessary (though you can optionally tweak it a bit).
