Oh dear!
The 5th time you've broken an aquarium?
How on earth do you manage to break 5 tanks?
I've broken one tank once by setting the tank on top of an uneven surface to measure it and it slid off the surface and smashed on floor when I turned around looking for my measuring tape! Doh!
Was a standard 10 gal tank, cheap anyway but still a pane to clear up!
Anyways, think would replace the glass with nice thick glass, not sure which glass is best, tempered or standard glass, think tempered is stronger but smashes into a million bits if breaks and standard glass more likely just to crack thus giving more time to save livestock if in time.
But replacing glass on any tank is quite a faff to do, removing old sealant, cleaning it, measure exactly for new glass, replace glass and new sealant and cure and test before adding water etc etc
Or if the tank is fairly standard, just get a new second hand tank, cheap enough to purchase from ebay or any online sales really if you shop around.
Personal choice imho, think personally I would replace the entire tank for peace of mind for me.
