tp bonus does (nothing) for VS
Well, TP Bonus attributes to Crit Rate. If I'm looking at it correctly, Godhands should be adding something like 7.5% Crit Rate when under 2000 TP and 10% Crit Rate when above 2000.
*BUT*
Godhands really only offers Higher Damage and is noticeably slower than Karambit and Karambit has lovely fringe benefits.
When I last checked, the DPS order was (From weakest to strongest) Spharai > R15 Spharai > Karambit > Godhands > Verethragna > R15 Godhands > R15 Verethragna and the difference between Karambit and Godhands was like 3% or less?
Absolutely love my Karambit and still have them so unless you are able to very easily pump out an Aeonic for your mule, I would just stick with those, like Eiryl said.
