Interesting question,
I'm likely the "odd ball" on the topic but I'll give it a go from my perspective since I reckon I have some experience here.
I regularly shot Steel Challenge, IDPA, USPSA, and the local GSSF matches. I found myself in a bit of a hiatus during COVID when matches dried up, ammo became unavailable and when it came back it was at supernatural pricing, etc but I'm wandering back into the competition rhythm lately.
It's been my experience that folks participate in shooting sports for various reasons and fall into different "tribes" as I'll call 'em.
There's the "true" competitors (which I am not), who spend countless energy trying to determine the most optimal combination of equipment to perform at their highest level during the game. I'd say that probably encompasses the largest group of 'regulars' because it's a competitive outlet for them from what I've seen. There's also the group that wants to see what the matches are all about and are likely on the more social end of personalities but on the lower end of firearm experience. I do recognize I"m generalizing there but just sharing my experiences and not trying to 'sell' my opinions as any sort of dogma.
Of course there's those that want to be there to practice reps with their 'carry/issued' gear. These are, from my years of participation, a group that seems to be dwarfed by the competitors/curious newbies exponentially but they certainly have a very unique approach and one of which I respect quite a bit.
As for myself- I'm that "odd/other" category who just like to get outside the house, be surrounded by folks of similar mindsets, and shoot. I'm not particularly motivated by having the 'best' of any certain element of equipment- I think "race/competition" guns are cool as heck but they don't have any particularly practical purpose as a firearm outside of playing the games so that's (for me) enough for me to be interested in learning about them/the approach but not to the point where I'm interested in purchasing one for myself.
I like getting out there and using "regular/factory" pistols with factory ammunition (certainly understand downloaded ammunition meeting pf giving an advantage to whichever game) but I'm only competing against myself at the end of the day. I like using my carry guns (and rotating through different ones/styles/platforms each month) with otherwise standard ammo because my personal focus is just getting out, practicing with standard guns/ammo in unusual range scenarios, and also using it as an excuse to shoot some pistols I've acquired over the years that otherwise would sit in the safe.
Reckon I'm just one of those 'variety being the spice of life' types. I'm personally fine placing mid-pack in local matches but get more enjoyment in my participation by rotating through different pistols/calibers and that variance essentially 'feeding' my desire to continue participating in the shooting games.
Hopefully that makes sense.
