I was with Absolute for just under a year. They were great, but I was getting Server 500 errors (out of resources). They doubled my resource allocation but every hour or so when cron jobs were running the CPU usage was once again pegged at 100%.
I ultimately moved across to EliteHost, who did the migration at around 21:00 (I asked for it to be done after hours). Once complete, they started poking around and had some... choice words about the way things had been setup. Not by me, but by Absolute. They made a few tweaks and said I must keep on eye on things.
The migration HAD to go smoothly as I couldn't have downtime come the next day, so my nerves were shot. During the migration, the owner "held my hand" over WhatsApp for the few hours it took.
Since then, I have gone from ~60 cron jobs per day to over 700 per day (not an exaggeration, I have 4 that each run 4x per hour, and dozens of others that run between once every two hours and once per day) and CPU usage has never passed 15%.
They had an issue about a month ago whereby a security update had a known issue with certain versions of PHP and there was no fix as yet. Instead of saying "hopefully a patch comes out soon," they rolled back ALL shared servers to a version known to be issue-free, even though I was the only one complaining. In their eyes, a bug is a bug and it doesn't matter whether it affects one person or everyone, it has to be sorted immediately. This support was also provided after-hours.
Lastly, giving you several weeks worth of free daily backups (free as in they don't count towards disk quota) with take a couple of clicks to restore in a worst case scenario.
Their support is excellent. Unlike Cool Ideas where the support I've received is great but I've only used it twice so can't establish a pattern, I actually DO make use of their support frequently when things go wrong, and they're always willing to assist in record time.
Since moving to them mid-2021, I've had 24 support tickets of which I gave 16 a priority of critical - I don't know if Absolute has changed, but you had to pay for anything higher than normal priority when I was with them.
It does actually make a difference, because if I mark a ticket as normal priority (eg a billing issue) it'll be addressed within 24 hours. If I mark it critical (eg site won't connect), it gets addressed within about half an hour 24/7.

Carbonite also uses EliteHost - that should tell you everything you need to know.
