I've used Noco chargers for years. I have a 2x g3500, a g7200, 2x 26000, and a Commercial 4 Bank. Then last year I bought a CTEK 25000 and a 4.3 Polar. I've had a couple of Noco go bad one showed up DOA and another died within a week one. I was finding that the Noco chargers were not fully charging batteries. After doing a bunch of research I decided to give the CTEK a try. And so far so good if I were to buy a new one it would be the CTEK 25000. I will say that the NOCO G26000 does a fantastic job of recovering batteries. I've used these chargers on everything from typical 12 V automotive batteries, to deep cycle golf cart batteries, to electric vehicle batteries, to 100AH VRLA batteries, to huge heavy equipment and stationary and marine diesel engine batteries.
If you have to have an old school solid state charger, then the Associated 6002B would be a great choice.
