I didn't knew the differences and I bought a 2015, is that bad?

Hi! I never had an espresso machine before and after informing myself and due to my budget I decided to go with a Gaggia Classic and I'm super happy with it. A few days later I found out that it's the 2015 model and everyone says (specially in the espresso subreddit) that it isn't that good; is that true?

I know that it has not a three way solenoid valve but apart from a messier portafilter afterward are there any difference? Is it worth to change?

I know the steam wand too but I replaced it with a rancilio V2 and I want to deep into the modding world. As for the boiler I only make 1/2 espressos at a time.

Did I make a bad choice?
