I still say it depends on your playstyle; if you'd rather have a run you can calculate, leaving only patterns you know you can deal with for the most part, go for greens, you'll be able to at least get the amount of lives you need to max out assuming you don't get any misses, though this only works under the assumption that you don't make mistakes - nonetheless, you still have room for mistakes.
If you'd rather rely on your overall ability and you know you can squeeze out a lot of air if you're working with no Bombs, go for reds, you'll definitely have a better time. I just hate the loss of Power.
