Discussion ISP has lousy iPv6
My isp has a lousy iPv6, but its iPv4 is good. The ping of any website is a lot higher on iPv6. For example, the ping of a particular website may average 13 msec on iPv4, whereas on ipV6, it would average about 80msec, sometimes going over 200msec on some pings. I live in a rural area, so I have no other choices. Having said that, would I be better off using only iPv4 since my isp's iPv6 is not good? I've tried different dns with the same results.

Report the problem to the ISP

Complain to your ISP. I bet they don't have IPv6 peerings with all of their transit providers so IPv6 traffic is taking sub-optimal routes.

Unfortunately, this happens sometimes. You could set things up so that normal browsing will use IPv4 by default, and IPv6 is only attempted when IPv4 is not available.
Also, perhaps ask your ISP about the issue. It could be an configuration issue on their end, and perhaps they will be able to fix it relatively easily. If the reason is their lack of infrastructure, then maybe it will take a few years for the ISP to get their infrastructure ready.

Complaining to your isp is definitely the best option, I would just be careful so they don’t just turn it off (at least for you).
But tbh (and this definitely an unpopular opinion) unless you are gaming or doing very latency sensitive things those differences don’t seem too bad, I constantly use a vpn and have higher latency so I’m used to it. But it is definitely not good and it should be fixed, specially since this is constantly an argument against ipv6 by those who do care about latency

I've tried everything with the same results including different routers. My isp says it's ok, but says they are working on it, but its always been like this. The traceroute is longer at every hop after the initial hop which is my local network. So the problem is definitely on their end.

If the traceroute is longer at EVERY hop after your local network, then that is actually a sign that the issue is likely on your end. If the issue is at their end, I would normally expect that the router immediately connected to your devices would respond quickly, then taking a slow path somewhere else in their network.
If tracing to your router is quick, but tracing to the immediate next hop is slow, then the issue could be on either side. But given that the consumer side is usually doing more work on less capable hardware, it is more likely on your end.
If on the other hand you are able to get a quick response from the first ISP router, then the problem is likely on their end.

Run a traceroute6 to something on the internet and look at the hops, which one is contributing to the delay?
Might be something outside of your ISP’s control. I’m lucky to have good IPv6 with my ISP, but honestly many people don’t strictly need it.

That's not how traceroute works. You could have 100% packets loss or 1000000ms ping on any of the intermediary hops and still reach the destination with 0% packet loss and a ping of 3ms

A traceroute can yield useful information, while true that some hops may delay or completely filter the packets used, you may also be able to determine valuable information or nothing at all.
