Tuchel yes. Frank no.
Frank's football would be fancier but not more effective.
Could see the fanbase turn on him fast, not to mention, the players when he stops smiling at them. Mind, Tuchel may alienate people with his Quantum of Solace bullshit, so it's a tricky one.
If we're looking in the Prem then I'd go for Marco Silva over Frank every time.
Fulham always seem to be pretty competitive in most of the games they play in, and don't often seem to get hammered either (I'm sure someone will pull up their results to prove me wrong in a minute...)
