33rpm vs 45rpm - which is better

Growing up, I was a big Peanuts comics fan including Vince Guaraldi’s music.

Recently, a remastered from tape “Great Pumpkin” vinyl was announced in both 331/3rpm and 45rpm, both are a single LP each at Elusive Disc. Both albums have the same number of songs.

It seems that playing slower allows for wider grooves, while faster may mean longer grooves. If so, I’ve no clue which one is better.

Which version offer the best sonics?
