I've never tried the module one either, but do have the regular JP trigger. I love how adjustable it is. Put a RRA 2 stage in my other lower and highly considering upgrading that one as well.
The module one looks a lot like the standard on, except just put together already with a bracket holding it together. I have no doubts its as nice as the one you have to assemble.
The only problem I did have with the trigger is I felt the hammer spring was a little light for mil primers. About 1/10 would get a misfire because of a light hit. Never any problems with any ammo except the XM193. Put the stock trigger spring on and its fine.
It does look like the module unit has the light spring on it. No clue if you are planning to shoot ammo with the harder primers, or if the trigger is able to be disassembled to replace the spring. Something to consider though.
