I've got the Mudclaws, Speedcross and a couple of pairs of Salomon XA Pros.
Mudclaws are great for mud nand slip - not so good on my final mile or so stretch back to the car on the tarmac.
Speedcross are amazing - can wear them all day, super comfortable too but as Nick says, they do wear quick on tarmac. Wouldn't swap them for the world off road though.
My Salomon XA Pros are the best. Really comfortable and confidence boosting on all surfaces apart from the really wet, muddy stuff. That's my choice for most occasions. Had probably half dozen pairs over the last 5-7 years, very rugged and long lasting.
Adidas are pish! Just don't suit my feet. Wasted 50 quid on them.
You say you really like your Mizuno - so at least you know their lasts suit your feet, so might be worth sticking with what you know. That way you can confidently buy online without trying them on. That's how I feel about Salomon trainers. All the variations I've bought have been perfect fits for me.
