i played significantly with both, the 97 rogues and use the 100 rogues (now mavrik I guess?).
The 97 rogues were awesome. Really good. Allowed me to start competing and holding my own with approach shots.
Once I got the 100's, my approaches took off and were getting spot on. You really don't notice the different meter speed if you have a ball similarly equipped (at the time I was using the 90 Titleist ball, now 87) but it is far too expensive to play with now a days. I use the level 51 Volvik and the 33 Callaway and the 100's perform quite well.
