The MKS Sylvan track have too big a gap on the back for the powergrips to go on. You can find some big washers to use, but you're better off going for one of the other two. MKS have smoother bearings than Wellgos, but there's not much in it. They're both fine.
Power grips are a lot easier than clips and straps, but they do sag and stretch after a while, becoming a bit of a pain in the arse, so you'll have to replace them fairly often.
I went to toe clips on one bike and clipless on the others. Clipless is best for me, but everyone's different, Toeclips with double straps are pretty good too as they keep their shape better than single straps.
