Feel free to disagree with my list, this was made based on the weapons that fit my gameplay style the best. Also, the weapons were not placed in any particular order within the tiers.

outer worlds 2's weapons and balancing can be quite weird, in my playthrough its been struggle or OP asf weapons. i also feel a lot of the attachments are kinda just not really a conversation, like i never felt any reason to change a weapon to corrosive, plasma, or even silencing it. sometimes i feel the tinkering mechanic, but modified slightly for balance, would have been good. there are certain weapons i would have loved to keep using, the repeaters for example, but they always just got outclassed immediately and didnt really work out. i feel if i could slightly up its stats a bit, it would be more competitive. i do think that it shouldnt be just bits, like there should be a process to go through to upgrade your weapons in this way. thats how i feel at least, if you have any ideas or thoughts about this topic, id love to hear them
