I have the big bear vault (which you are welcome to borrow) that I keep around for when I can get my whole family backpacking.
Last year I got the small lighter1 and have become a fan. I agree there advertised weight is deceptive, but it still has a pretty competitive weight. If you plan to use the lid as a cooking pot, then it is a much more competitive product. There is a pretty long debate about the dual use nature of this product over at bpl, but it makes sense imo.
I don't have experience with bearikade, but I will say it failed grizzly bear testing so don't buy one expecting to use it with your Canadian grizzlies in the future. Renting is a great option. They also scale there cannisters (you can get it almost any length you want between limits). That might be a great option for you to get a mega cannister (not sure if they rent those though).
