Cruisers are perfectly fine, if you are OK with the heavy weight and relative low power. Also remember that they aren't very good in the twisties (you drag hard parts relatively easy).
I had two cruisers, and they were perfectly fine. But I bought my Katana as I wanted to go faster and be able to turn faster. I was convinced that I needed a sportbike after shredding the muffler of my 250 cruiser while turning. The muffler was so bent, scraped and smashed that I replaced it with something with more clearance.
Then I found that I was dragging the footpegs, and didn't felt comfortable, as I could basically turn faster in my cage than in the cruiser, as it was dragging hard parts in relatively low speed turns.
But if you like to ride long distances with relative ease, you will be fine with a cruiser. And there is ton of aftermarket out there for them, you can also find parts to increase ground clearance and make handling better.
