Of the motors you mentioned I would say in order of performance (lowest first)
Hyper 8 Port
OS RG
Sportwerks .26
In order of price (lowest first)
OS RG
Sportwerks .26
Hyper 8 Port
never seen a sportswerks .26, so know comments about it.
performance wise i'ld rate the hyper 8 port above an o.s. rg on anything more then a tight technical track. rg has alot better bottom end but a properly tuned 8 port will run it down with a little bit of room.
In saying that i'ld run an rg. over a 8 port 'cause the 8 ports aren't as good a quality motor.
i'ld chose a pbs over the tq.
i never broke a thing on my pbs, nor seen anyone else break one while at my track , but i've seen a few guys break knuckles on the tq. first time out at the track (i don't know how much upgraded knuckles are, but i'ld guess they would hurt your pocket a bit).
