I have two Ultum Nature Systems 5N tanks...roughly 5 gallons, and in the next few days will either buy a 9.6g Landen or, possibly, the 11.3g Hydra Aquatics. Not because I don't like the UNS tanks, but I became annoyed with the vendor and UNS over answering the simple question of "who sells the glass lids with clips" and never finding a vendor, despite the UNS saying otherwise. I think a general trick to tank longevity is to not move it, don't use razor blades by the silicon and when you do move it, empty it out, first.
Also...I confess to loving the rimless look with mitered edges. That's a winner look for me.
