Depends.
The frame and forks package that best fits your build, and rides best, might be the one with the low rent spec. No point ordering a super value mail order bike if when it arrives it's not really "you".
People get really hungup on "spec", as if anidiot like me could really tell the difference between say deore and lx blindfolded, on a cold muddy day.
My first decent mtb was an old Orange c16. It got stolen but was still the best bike in the shop for "me" at my price range. Indeed, it was £150 more than the marins/specialiseds I looked at, and with a lower rent spec, but the frame, the geometry – was just great for me, and rode in such a zippy, whippet way that the cheaper, better specced bikes in the shop couldnt.
Only way to tell is to ride them…….
dont get hung up on thinking a bikes better or worse than another just because the odd part is a couple of quid less or more than on another bike.
