Trojans, in a landslide!
I have had six Rolls golf car batteries and four trojans. The trojans outlasted the Rolls, and for WAY less money. I know what Practical Sailor says, but I doubt if it comes from actual long term experience. Look at it this way...the largest market for the type of battery we are talking about is the golf car industry...as a golf pro, I can tell you that Trojans are huge in this industry. I will bet that you cannot find a single golf pro or golf course that has ever heard of Rolls! And golf courses are not operated to loose money.....I tried Rolls and am convinced I paid for snob appeal and hype.....and I did it TWICE!!!!!.
