I've also been looking into other brands in the same price bracket and there's plenty to choose, I wondering if there's any opinions on the brand garmont:

I've not seen the Garmont Pinnacle GTX but it's a crampon compatible 3-4 season boot designed for heavy backpacking and mixed mountaineering ideal for UK winter and for summer alpine use
not walking on "fairly even" terrain in the Yorkshire Dales with an odd trip elsewhere on more demanding terrain. I'm pretty sure you would find it to be far too stiff and uncomfortable for the type of walking you described in your first post particularly if that involves covering long distances.
Your choice of boot type needs to match the type of walking you do the most. In my opinion you need to be looking for a 3 season boot which has good all round capabilities over a range of terrains. Both the Altberg Nordkapp and Tethera fit the bill and although not specifically rated by Altberg for crampon use both models have been used with C1 flexible crampons in winter conditions by a number of members on here without problems.
Yeah the high rubber rands on the nordkapps look pretty good, I've never been into the full leather look but I like the high rands.
It's really not a matter of whether you are into the full leather look or not.
It's not a fashion show and it really doesn't matter what they look like as nobody cares - it's about obtaining the best performance and value for your hard earned money!
It's about buying the right type of boot for the type of walking you do most and, provided you maintain them properly, boots that will last.
A fabric or fabric/leather combination boot may last you 1-2 years at most if you are lucky. When the waterproof liner fails (and they all do at some point) the boot becomes useless in wet conditions and needs replacing.
Similarly a suede boot may be fine for use in cold dry or snowy alpine conditions but is useless in the UK's almost permanently wet climate. Suede is difficult to maintain and when it becomes waterlogged it becomes extremely heavy and takes an age to dry.
By contrast a well maintained full leather boot with minimal stitching should last you 5+ years with maybe an odd resole depending on mileage covered. Provided you wax it regularly it will still be waterproof and usable even when the the waterproof lining has failed.
From that I hope you can see that the best value for you is obtained by choosing and buying a full leather boot with minimal stitching.
If you do end up buying the Altberg Nordkapp I would strongly recommend that you decide to wax them as doing that will save you a lot of time and effort maintaining them and increase the life of the boots. Bear in mind that the nubuck 'look' is only designed to attract shoppers who see them on the shelf or website and think they look nice and for no other reason.
