Green label or Magpul?
If you want a bunch of standard M4/M16 mags without spending a mint, the green labels are a good investment - it's hard to go wrong at $6-7 per mag. However, I'd avoid the larger mid-caps since the more rounds you load, the longer the spring-well needs to be, and the more bends along that well. I use the 75 rd green labels, and they work very well.
For the Magpul PTS ones, yeah, I think they're worth the money. Just be aware that you'll be spending more on them. Also, I can't recommend anything that hold greater than 120 rds (because of the potential for the follower to bind; mainly because I prefer reliability over everything else). With my SR25 mags, although they can hold 140 rds, I usually only load them to 90-100 rds, simply to avoid binding issues.
Overall, both are good picks - it really boils down to personal preference and money.
