Do they? All of them? Or did you go out for a dinner / drink / orgy where some Spanish people were who smiled and nudged because you asked for a sandwich instead of the lube?
And what makes Spanish people better English speakers?
Ok, let's try again:
How do you know the Spanish will "smile and nudge you on encouragement" if you fail?
And what bearing does their ability in English have when deciding to learn a foreign language
In my experience, people in most countries will appreciate you making the effort to try, I specifically remember my parents mentioning this talking about when they moved to Italy.
It's a seriously huge commitment and one that I very strongly suspect you won't manage .
Yet here you are wanting to learn to speak a foreign language, fluently, and you base this massive decision on a "recent experience"?
Ok. I was sort of hoping you'd be able to piece it together from my last post but evidently not so here we go.
My point is, learning a foreign language is indeed a wonderful thing and I will genuinely applaud you if you pull it off despite not living in that language's native country, but there are tons of different languages out there and basing your decision on "a recent experience" is silly. It's your decision, learn Swahili if you want, but make sure the choice you've made is the one that'll benefit you the most.
