It's said that the only difference between men and boys is the price of their toys.
Guilty as charged, Your Honor.
I've been brewing for more than 30 years. It's a hobby, and partly an obsession. OK, maybe the other way around. Been through buckets, carboys, Better Bottles, etc., eventually progressing to SS Brew Buckets, conicals, kegmenters and a unitank. Of the stainless gear, I still use them all. Different tools for different jobs. Your first step should definitely be away from plastic and glass, and into stainless steel. The only considerations should be whether you can truthfully afford it and whether you will actually use it.
Bling is way cool. Making great beer is 'fire'. BUT. You don't make great beer simply with bling. It takes ingredients, process, sanitation, temperature control, knowledge and experience. The only way you can 'buy' your way into better beer is to find a better beer store.
I know I'm making better beer now than when I was using buckets and bottles. It's not due solely to flashey equipment, though the gear gives me a great deal of satisfaction. I don't need to justify the expense and probably would just waste time trying to. Fortunately my situation is such that I don't have to.
So simply ask yourself, can you afford it, will you use it, and will it bring you joy? If any of the answers are "no", then you probably should not. Of course you could always sell it later....
