For me it was a constant battle with Chromium. On 16GB of RAM it simply wasn't enough. Every other day I was hitting the OOM killer or system freezes.

I was so angry I went and upgraded to 64GB of RAM and now it's stable. I found out that I don't use any more tabs than I have in the past, with gobs of RAM available. So I believe it's just the web getting more bloated over time along with Chrome getting more bloated. One day I suspect I'll be running the same number of tabs and 64GB won't even save me.
