I've used Jira at dayjobs, and presently am using clickup at my small business (we are on a paid plan). I like clickup, but it is _too slow_. It is soooo annoying to wait 5(!) seconds for every page load. I wish I could get a simpler, less-featured version, with uglier graphics, that loads in 0.2 sec. If you have made something like this, send me a link and I'll try it out.
If clickup folks see this: please make it load faster.
There are things that are worth being patient about. Jira isn’t one of them.
“Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.”
Another interesting dynamic -- it may hard to tell if some tool is fast enough during early evaluations. I believe clickup was fast when we first tried it, but now that we have lots of tasks in it, it's slowed down. This could just be my poor memory though.
