I would only go for an all in one tank if you don't plan on replacing anything. A lot of people buy a Fluval kit or similar, only to replace everything but that tank.
I would personally go with a Mr. Aqua of your choice and add filtration and lighting, unless you really plan to keep most of an all in one tank.
this is what i plan to do, get a Mr. Aqua and just get a small nano HOB and clip light. But nothing wrong with the kits either.
