I know you said you hate them but have you tried a logitech g300? I have one and the buttons are on the top of the mouse on the sides and middle. It's very comfortable and I haven't had any problems hitting buttons accidently when lifting the mouse.
I'm using claw grip as well and I'm playing with the orignial Logitech G300. I absolutly love it because it fits my hands perfectly and has six customizable G-Buttons.
Logitech G300. Its the mouse I've been using for about 3 years (although 1 of those years was spent in a shoe, you can thank my sister for that one). Has 6 assignable buttons and 3 switchable profiles. It is super ergonomic and I can use it for hours at a time with out my hand getting tired. You can buy it here
The Logitech g300 is very similar, but no accidental clicking of side buttons
My hand is small and i use this one: https://www.amazon.com/Logitech-Gaming-Programmable-Controls-910-002358/dp/B005EWB3AU Logitech g300 it have 9 programmable buttons. I play mostly mmos with it.
G300 or G300s or Tt Esports Ventus or CM Storm Recon or Roccat Kova+ or Roccat Kova might be worth a look.
I have a g300 I'd say something like $15+shipping, I can get pics if you're interested.
