I own both (BW is there only machine I have owned twice). I have more time on Baywatch and prefer it more right now.
4 flippers with lots of ramps and wireforms on Baywatch. Color DMD is awesome.
3 flippers and great flow on Demolition Man. I keep the claw on though others disable it to improve the flow even more.
Code isn't extremely deep on either but shots are satisfying on both. Mode start for Baywatch is shooting a shot 3 times but the modes themselves will vary.
I am going to vote for Baywatch but you will be happy with either
