converting from bootstrap to materialize

I would say materialize is more "finger friendly", as you get, out of the box, support for finger-actionable navdrawer, finger-dismissible snackbar, touch slider... (see images).

Bootstrap 3, as far as i know, does not have such support. Bootstrap 4-alpha is coming so maybe they add such ability.

Bad news is that materialize seems to lack, right now, the team that bootstrap has. It's freezed in v0.97 (personal opinion: feels like the team doesn't have the time to go on). Time will say if the project continues.

Also, there's a new competitor in town, google and Material Design Lite (http://www.getmdl.io/), but also, it still has not finger support (eg: see template http://www.getmdl.io/templates/dashboard/index.html)
