I don't really want to jump on a band wagon of giving someone a hard time over potentially poor choices, and yet it has to be said, heavy duty tools and tools designed for specific jobs if you are doing that job a lot are a must, if you have trouble believing that then try doing your domestic cooking with your bushcraft knives for a few days, I have and only the thinnest and sharpest ones like a new Mora go half way to doing a good job, the same would go for processing wood with your kitchen gear, similarly no matter how well built or designed a multi tool will get you out of trouble, but it will not be comfortable with many of the tasks it can do, nor will it stand constant heavy use.
Then we have axes/hatchets both are similar and yet different horses for courses, both look easy and yet neither are, they require skill to work efficiently and safely so be careful out there
Watch a tradesman, I was an electrician and it's fair to say we often lean toward a tool we use lots to do jobs it isn't designed for side cutters become perfect pincers, bottle openers etc, because we are "at one" with them, my dad ( a butcher) could do things with a big meat cleaver and his butcher's knives which unnerved me almost to the " I can't look" point and he was old school ( Like Jansman I suspect) from an age where chain mail gloves and kevlar just were not thought of and skill levels were so high that other than very minor nicks were rare. Watching a skilled person at work is a sight to witness and to be honest something that as we get older we take so much for granted that when we see inexperienced people trying stuff out, it can come as a shock.
Another thing I'll throw into the hat is that there does seem to be a perfect tool even from a dozen axes for example, if you could pick them all up and try them one after the other it would be like Harry Potter's wand

where one will stand out above the rest as the one for you, and returning to the OP bug out bags - rucksacks are the same no matter how good, how well designed or durable they may be it'll still be like Dolly Parton wearing Lindsey Lohan's clothes if its not sized to suit your body, for my part I'm finding some particularly smaller ones very uncomfortable, it's almost like shoes if money were no object ( and I'm going rush 72 because my son has one and I like it) for any bag a shop like sports direct with a huge selection is the place to go and wear what you would want to be wearing when using it too as that makes a difference too, you may find a summer and a winter version a must because you're essentially a different shape dressed for the cold.
I'm still going as cheap as chips ebay stuff for HOBs or anything not expected to get much use, but for every day or frequent use I want something good, and comfortable, truth be known I could do with a 2.5 ton truck for all the crap I'd want to bug out with and an army of Sherpa's to carry it all (including me

)
I have a strategy, it's not written in stone, nor can it be, this scenario has too many variables, everything about it depends on those variables, being specific is not possible.
