TM is so 2002. Seriously install a 350-380 fps spring (what most modern brands use) in your TM and it won't last. Now for a BA and some GBBs, it would be good advice (or for their new recoil'ed SOPMOD/SOCOM) but their old models are, well... Old and outdated.
If you have the money... Nice AEGs are VFC, Realsword. G&G canshit are canshit. They full metal line is mid-level... Ain't bad, but ain't the best either. G&P has their flaws but are pretty good.
IMHO ARES are great, however they are not 100% compatible with TM-spec upgrades and replacements, so in case of breakage it's harder to fix.
