I always use regular spins because I want to choose the amount I want to bet, instead of being locked into fixed spin amounts. I have my own strategy when playing slots, but I believe that luck is everything in this game so no matter what type of spin you use, the result is basically the same.
When you buy a free spin, the bets are still fixed, though may be you mean is that buy features are making the game faster and you just prefer the slower way of losing. But we are on the same shoe. For me this is more fun, though I think a true strategy is different from choosing whether we play the manual way or buy a free spin but you are right that slots are still luck-dependent.
I only heard before that buying a feature has more RTP than playing it the other way. I sometimes think it was true because that is also what I observe from other slot players. Oh well, May be I will only try that once I have more cash in hand
