Heater quality, which is where I think a lot of reputations were made, was a bigger issue before digital controls. I had ebos that lasted well over ten years - I had one from the nineties that just became unreliable last year.
I find now, when I have a mix of ebos and fluvals, that that are quite interchangeable, and quite good across the board. Pre-digital, I had a few brands kill entire tanks, but those days are hopefully behind us. The reputations have stuck, even though the thermostats rarely do now.
I don't use many heaters, and when I do, I have 2 per tank and am only heating a few degrees above room temps. For the fish you're going for
@gwand , they are good from 23 to 26c. If you are breeding them, some experiments have shown Moliwe to give you close to 50/50 sex ratios at 26. I bred them at 22-23 and only got a slight excess of females.
No tank here goes above 26.
