I have a /56 at the datacenter and Google Fiber gives me something like a /64 or something so I have full IPv6 connectivity everywhere. For the most part this is fine, but I've noticed the Internet is 'less reliable' on IPv6 and so in my head I still feel like it's a little iffy. There are times where a AAAA record points to an IP that doesn't respond, but the A record responds and so on. I just think it's the same as my blog's Gemini protocol server. I don't use it and offer it for fun but it's a best-effort basis. If it went down for months I wouldn't notice.

Man a /56 is not as big as you think. I'm an IPv6 neophyte but I'm starting to think about /64's the way I think I think about IPv4 /24's but 802.11 /24's y'know? So Google Fiber giving a you a /64 is the same as saying - would you run your home network on a single /24. I mean ... you could but it feel like saying could you have one pair of shoes. XFinitity gives me a /60 and honestly I feel unhappy about it. At my modestly sized job site we're easily using a couple 100 /24's - and I'm not in network operations so that number is probably wrong.

Just for fun and bitterness I checked on Google Fiber. "Google Fiber generally hands out a /56 IPv6 prefix delegation to residential customers, which allows for 256 subnets of \64's) each." Totally confused as to why XFinity only gives me a /60. I think it's a benefit for people who get the business class - that is a /56.
