I switched a few years back for the same reason, rotomolded cooler's I had were to tall, went with Coleman extreme's hold ice as well as any of them. Side note The 100 qt plus rotomolded coolers are heavy even when empty.My 120qt Coleman Xtreme 6's are just over 18" tall and work very well for a week. But I think they went and changed them up because I haven't seen them in stores the last couple years. They used to be about $50 which was a great deal. Now their new ones are probably over twice that amount and won't work as well. That seems to be the trend with everything these days. But quite frankly, there are a lot of decent coolers on the market today, if you can find your right size.
There's "best".........where money's no object. Then there's "good enough" at decent price points.
