In terms of their overall output, I think Bach tends more toward music that sounds complex, heady, and ornate while Handel's sounds light and lyrical.
For example, listen to the unfinished fugue in C minor, BWV 906[1]. Once all the voices have entered you can hear how there is a kind of game where Bach is trying to cram as many cross-relations into each measure. When he starts sequencing that disjoint tail of the melody it's about as dissonant as music from that period can get. If you heard three people singing this a cappela you'd think they were from Mars.
That's certainly experimental, but there are many other pieces/moments by Bach that are similarly jarring. I'm going to rankly speculate that there is nothing in Handel's output even close to that (in the hopes that it spurs a contrarian to provide me a link).
