Welcome Pete!
My advice on how to choose ...
- The first one to reply.
- The first one to have a meeting.
- The one whose meeting is nearest to you.
- The one with the nicest stickers
- Whichever one you prefer!
Seriously I'd suggest if they both have meetings fairly soon, go to both, meet them, have a chat and see who you feel you get on best with. You can shop around a while and register an interest with both, then decide.
One group seems to have Jeep tendencies lately but I'm sure they're lovely really!
Your experience, suitable vehicle and tyres sound great whichever you decide on.
