Stars show the popularity of this repository in the community.
Latest commit show how active the contributors and members, sometimes I check the commits of other branches like dev because not always master is the main branch.
Too much issues also mean the instability of the project ?
Of course i prefer too much issues than having no issues at all. It just means that the project demand is high !
I usually go with stars and latest commits, if I am in doubt I check also the issues activity (when a issue was opened, resolved, etc)
Thanks. Could you explain more why you consider those as the most important factors ?
That's about it I think

It means that demand is high as you say, I wouldn't say instability.
Take React as an example there are 276 opened issues there...
Sure. Some maintainers are just lazy enough to close useless and out-of-date issues ;)
