Adding to the two posters above, going with the more commonly downloaded "realistic" models will keep you pretty well covered, minor differences, one might suit your needs better in one case, then another the next time. If you use lora/embeddings you might need to use a specific model for "best results". Depending on what you consider "best results" at that time.
I strongly advice staying away from low tier "merges" that's infesting things though. Generally those are poorly done and are leaching off of other peoples work, often without even bothering to give credit to those they are stealing from. And you end up having to fight issues with your renderings that you shouldn't have to deal with simply because others have taken shortcuts etc.
Depending on situation/imagery, i've had pretty good results with these, just to start off with:

If i'd have to pick just one i'd probably agree with
Jimwalrus and go with cyber. It's being updated/worked on pretty often and has inpaint model too. So if bandwidth or hdd space is concern, i'd start there, and as
Sepheyer mentioned, sampler matters too, so try different ones and see which you like.
