common knowledge is that a full face disk has significantly less "chatter" on engagement. what i notice with my stage3 is that it chatters or engages rough only when i milk the clutch. if i drive it like i usually do (dump the clutch, but at real low rpms. dont jerk the car, just barely enough gas to make it engage. let it start rolling till it gets to around 1000 rpms then hit the gas (daily driving)
when i race it feather it just enough to load up the axles and then dump the clutch. so it'll move about 2-6 inches then the weight will transfer. if i try to launch at a high rpm it does wheel hop. with nitrous it will wheel hop after i shift into second, also. which puts me toward any direction but straight.
so my opinion, use the 3+. it'll last a little longer (assuming you know how to drive well) and launch good. the only downside is it'll weight more than a stage3. good luck!
(oh and the biggest issue with daily driving is if the hub is sprung or not. if its a solid disk with no springs, you may want to reconsider. the solid hubs are a terror on stock motor mounts, stock diffs, and stock axles.
