I wouldn't exactly call it great. Most user groups have tons of reports of issues, they seem to need to fuss with it every update, and if you aren't careful with lots it can burn out some SD cards.
I’d say issues are a pretty small group of people, it’s just that it has a lot of users.

Updates are seamless almost every time?

Cheap SD cards don’t like Databases, expensive one’s still might have issues. But you are neither forced to use SD cards, nor an rPI with HA. I used to have a PI4 with an SSD, and nowadays a VM on x86 hardware.
But my main complaint is how high maintenance it is. I do think they've got a little bit better in the last 6 months, but it used to be there was a intentional deprecation and breaking change in nearly every major (i.e monthly) update. Updating requires carefully reading through the change logs.
Then once you've fixed your configuration, that update might have fixed some bug you've been having only to introduce a new one.
My installation spent the better part of the last 12 months with at least one annoying bug at any time.
I run it as VM on a tiny Proxmox < €100 server that also runs a bunch of other things.
I’ve been using HA for several years now, I almost never have update issues, updating on every notification. I had a tiny incompatibility this major update that only made issues with once HACS component (community store, not tested by base HA). The last actual issue was some time mid 2022, and even that wasn’t major.
Only if you buy new and get something much more powerful.
I run HASS in a VM on an old small form-factor desktop they were going to throw away at work. The most expensive part of that PC (that I paid for) is the quad intel NIC that I use for my router VM. It can NAT + FW (pf) + VPN (wireguard) at gigabit speeds without breaking a sweat.
This is an HP EliteDesk 800 G2 with an i5-6500 and 32 GB RAM. Similar boxen can be had off ebay for peanuts if you don't live in the boonies (or you'll have to pay for shipping). They may consume more than an RPI, but they are very quiet (I run it 24/7 in a studio apartment and am very sensitive to noise). They're also able to do much more than said pi, since they can use standard off-the-shelf components (regular DIMM RAM, regular SSDs, regular expansion cards, etc).
When I do logging I buffer in ram and dump all at once, and often I just save min/max/avg over a period rather than every transition.
Tons of users with tons of different integrations means tons of issue. That is true I suppose.
I have a very simple Homeassistant setup with a few different zigbee lights and sensors. It has it's issues but 98% of the time it works just fine. The 2% that are frustrating are issues with zigbee connectivity but homeassistant works pretty well. I'm still not a fan of the yaml configuration but that is being worked on.

more of a hardware issue (raspberry pi) than a software issue.
I run it on an intel nuc and have no issues with SD cards.
