Both latest Chrome and Firefox does really well with lots of Tabs. Spending a lot of time to optimise the Browser for Muti tabs environment all while being responsive and causes less Jank. They will freeze and unload old tabs from memory. A List of Tabs that let's you close them with a single click. And Search for Open Tabs.

Compared this to Safari. Not only does opening Tab Overview will reload most of your Tabs, meaning you will either crash your browser due to memory pressure, or you create so much paging Data you write from 100s to 1000GB to your SSD. Quite literally killing your SSD. It also does not freeze old tabs or unload tabs. The only way would be you quit Safari and reopen it often. It is also the slowest browser once you have multiple tabs opened.

These issues had been with Safari for at least 5 - 8 years and even in Safari 18 it doesn't seems to be improved.
