i'm not going to try to talk you into or out of any pack, just adding a little context...
if you buy a stone glacier, kifaru, or exo in your size, you can try it and see if it works well for you... if not, you can resell it for a small loss, and try another.... if you buy a different brand pack, you will take a bigger hit on resale.
i'm not going to recommend any specific pack, i have pretty much used all of the normal high end packs besides SG (i don't want a 26" frame, so i will likely not try them) they all fit a little different and perform a little different on my back.... my favorite and best fitting pack may be the worst for you, kind of like boots.... what works for me may not for you.
my least favorite pack i have owned was my kuiu, but they have improved since i owned one, but load handling aside, i tore it up pretty bad in a season of use, and ate load lifter straps like crazy.... it's the only pack i owned that had durability issues. some people love them and have no problems with their durability. before i sold mine i got the newer belt and suspension, and it was more comfortable, but it still wasn't for me for several reasons.
MR are super tough packs, and love my pop up for it's niche, but didn't care for the guide lite frame (didn't have the MT version) i think that was a "me" thing, and not the frame.... if they fit you well and handle weight well for you, they are a solid option.
the last few years i have hunted with and hauled heavy loads of meat with HH full curl (pretty good budget pack, just heavy and clunky) MR guide lite and pop up, kuiu, exo k1 and k2 (love exo packs) seek outside, which are awesome lightweight packs, just don't fit my body great, and just got a kifaru.... don't have enough time under it to say much besides it has high potential for being a great pack for me.
there are lots of great options these days. if the seek outside fit me good, it would probably be my #1, so lightweight, adjustable, and just nice packs.... i am one of the few i have ever heard of who didn't like their fit, most love how they haul weight, and their prices are pretty dang good considering the platform.
weigh all of your options, know the first pack you buy may not be the one that fits you best or works for you best, know that pack fit is personal, so no matter how awesome someone says "..... pack" is, it may not be for you.
buying used is another option.... buy it, try it, and if you don't like it, sell it for the same price and try again. don't compromise on a poor fitting pack, you will be wearing it a lot, and if you find the right one, it's a long time purchase.... good packs last.
