Hi Jan, Welcome to the forums!
Quite some favorites you have, excellent choices. I have not tried the Coal Ila 25yo, so I can't compare it but it's sure to be a great dram
Highland Park, Ardbeg, both also have great older expressions, but please, do not forget about the younger expressions! It helped me a lot to appreciate the older expressions by trying the younger ones first. This helps getting accustomed to them, and it saves you money as well
Good luck on your journey through the wonderfull world of single malts
