Chipley Machine CCM T2 is my favorite...I have not shot a CCM J12 yet. When I get mine, I may need to update this post, for now these are my choices.
CCM S6.5 shot the same as a T2. Mostly just a different look and a single pump arm. If you like the way to looks more than a T2, it’s a great choice as well. I prefer the smoother lines of the T2.
While I like the way they look, I am not a fan of full-blocks, just not fond of the extra weight or the scratched-up goggles, though if you are the CCM J2L or Series 6 are both great markers. The J2Ls are rare, only available used and can cost more than a new S6, so if a full-block is what you want get an S6.
CCM are the best value in paintball.The value of CCM markers are based on the quality of materials, workmanship and service rather than technology and fashion. Purchase a DYE DM-12 last year for $1300 last year, see it for $600 this year. Buy a CCM T2 last year for $700, sell it this year for $600.
The BL MVP is a good marker, nice quality, just does not shoot as well as the CCMs. They are very consistent, mine shoots +/- 2 fps.
The Phantom is a good stock class marker, does not compare to the CCM or the MVP, but it runs on 12s and looks like a space gun. Unless you are committed to stock class, not a great choice for a first pump marker.
If one is on a budget, the Empire Sniper is a very good value and has a low price. Good mid-block design, comes with a barrel kit, locking feed-neck clamp, on/off ASA, Hit-man mod, good trigger, etc...Like I said, a really good value, just mot near the quality (or price) of the CCM products.
If you are asking this question, you should stay away from Autocockers converted to pumps. If you are an expert (and you are not), you could get something really great, but a lot of these markers are cobbled together from worn and mismatched parts and do not work well. I have a few friends that were turned-off to pumping because they started with these sloppy and unreliable excuses for a pump.
