I've had Altberg Defenders, Haix and Karrimor SF boots over the last few years. The Altbergs were OK, the Haix nearly crippled me and the Karrimor are a good, comfy boot but I find they "creak". However, I've recently treated myself to a pair of Grisport Gamekeeper boots. They are so good, really comfortable straight out of the box, appear well made and have plenty of toe room (wide fitting). I've used the excellent Grisport Dartmoor shoe/low boot for years which prompted me to go for the Gamekeepers. I know what I'll be be replacing them with when the time comes. They won't break the bank either.
