For me at least, the auto fill feature in LastPass didn't work half the time. Simultaneously, LastPass doesn't let me copy and paste my password without opening up the 'Edit' page for that particular username/password entry. In Chrome, the autofill feature didn't always work either (but it did work >90% of the time). However, I could just click the little 'LastPass' logo that popped up in the username/password field and click the 'Copy' button on my password.
For uBlock Origin (or rather, the fork of it since the actual developer abandoned the official version due to the difficulty of developing for Safari), I _hated_ how the icon in the toolbar displays the number of elements blocked in a big red badge that you couldn't turn off. I couldn't just remove it from the toolbar either because uBlock Origin frequently blocks what it thinks is an ad but is actually a critical part of a webpage. The only way to show the webpage correctly is to disable uBlock Origin for that webpage. And the only way to do that was to click on the button in the toolbar.
One of my favorite extensions for Chrome is 'Disable HTML5 Autoplay' which just blocks HTML5 videos from auto playing. Safari has no such extension.
I also hated how when you type in a web address in the omnibar in Safari and hit enter, half the time there would be no response (i.e. no loading bar, no change in the tab's contents, etc.). I don't actually know what's happening behind the scenes, but a refresh usually fixed it.
LastPass: I know from personal experience that plugin is garbage. No argument there.
There are extensions for blocking HTML auto-play. There used to be one called ClickToFlash, which became ClickToPlugin. I don't know if it's renamed again but it supported that.
The address bar thing is just weird. Can't explain that.
I won't deny that there aren't many extensions for Safari but I've never minded that, they largely never seemed necessary. For the longest time the only one I used was ClickToFlash. These days I have 1Blocker, but I've never been a plugin 'power user' even back when I used FireFox so that doesn't really bother me.
I looked into ClickToPlugin. The developer ended development because of Apple's development policies [0].
Also, I just remembered: the big extension that Safari was missing is Reddit Enhancement Suite. I could've lived with Safari if just RES was missing. However, in summation, all those issues made me decide to switch back to the RAM/CPU/battery sucking Chrome.
