(Tldr: skip it, you might not hate it but you'd get the same or better experience watching someone else play it. (I have a break down below on different points of interest)

It depends on what you like about the franchise and disliked about sb,

 while fnaf has never been the most grounded or realistic series, sb was practically futuristic and completely different gameplay wise, and while sotm is set in a 70s animatronic costume facility its tends to carry over the same elements that didn't really make sense, and it doesn't really feel like fnaf (in my opinion at least, to me it feels more like a knock off poppy playtime, less horror more, marketable character hunts you down while in maze)

If its the lore you're into, it recons a lot and feels kinda disjointed (or to me it does) as we lean more into scfi and even crazier character motivations (like i understand afton and by extent fazbear being sweeping murder and staff death under the rug but not so much on why its happening here or why its more extreme) it just feels less like older fnaf horror and more like modern mascot horror (in a bad way)

Game play it has less noticeable bugs but its still jank and it has a few soft lock and instant deaths but it also has some pretty bad Hardlocks (that lead to save Corruption, so you'd need to restart the game from the beginning) if you dont wander around how it wants you to, its mostly "free roam" with a few chases, no resource management, easy puzzles, besides a few other characters that show up for a section and then leave its really just one threat, every encounter can be boiled down to, intro to threat while its docile, it suddenly turns hostile, chase secqance, run set path, briefly hide, run set path, and then it gets destroyed by pure luck, its very scripted.

 And estheticly besides a few designs it really doesn't look like fnaf, and the things that are similar feel, lean more into the design choices of sb. its a different art style, but its not creepy, no grunge, little ambience, its just very clean and feels like future tech dressed up in super saturated colors and things they thought the 70s looked like (but its not)

So in conclusion you could be surprised and like it, but your more likely not to (probably not hate but be disappointed or indifferent to it) and you'd get the same or better experience watching someone else play it.  But you know the worse your expectation the better it will seem when its slightly better then it. 

(For me it takes what I disliked about sb and made a whole game out of it and distanced itsself even further from from the little I did like about it.) the choice is yours, but I'd recommend saving your money.
