I think that removing it is a bit excessive, perhaps retiming it is more appropriate. But I notice I'm kinda late to tell that since it's already remove :p
But to answer your question, the HTML version is by far faster than the Flash version because of the candy falling speed have been increased. By far as I know the HTML 5 and mobile version are more or less the same, so I would say only Flash is slower.
It had come to my attention that the weekly booster bonus (Monty's and the alien's event) has arrived in the HTML 5 version as well as being already present in Android / iOS. Since those are not bypassable by my knowledge, wouldn't it be wise to separate the caterogies by Boosterless / Booster No IGP? I mean boosters in most of the levels are significent advantage over "boosterless" even as early as lv. 7 and the entire board have boosterless runs (I think).
I'm EDav1123, I've been watching TAS and speedruns for about 4 years now and I've decide to give it a try. I'll be thankfull if you guys suggest me a good video capture software.
