This has also been on my mind as well recently.
I've been using Sublime for the last three years and I've been very happy with it so far. I've got everything set up the way I like, the multiple cursors are fantastic and the keyboard shortcuts are set up just the way I like them. It's minimal, stable and lightweight even after a day's worth of use.
I have a growing worry at the back of my mind however…
The author of Sublime Text release very, very, very rare updates. While people who know him on the forum keep telling the community that it hasn't been abandoned I worry that it's falling behind and becoming abandon-ware. Last I heard he was going to finish the current beta off, then get other developers on board - that was at least 8 months ago now
When I have some free time I'm considering PHPstorm - you can sync settings between machines without plugins, it supports a lot of Syntax and I've been impressed by another product by them: Data Grip (their new multi-database IDE). It's Java, which gives me a little bit of worry about performance, but it does have some nifty code refactoring tools and is generally always bang up to date for supporting things like PHP7. If I do decide to move over to it I would most likely configure it to have the minimal interface of Sublime (no line numbers shown - use goto shortcuts and the status bar, no file explorer, no menus, no minimap - I do everything from the omni bar and via keyboard shortcuts).
Atom is another contender - I hear it has improved a lot since the early days. I'm a bit unsure about the whole "Web page as an editor window" but it's free, so I have nothing to loose.
Vim some people have bitten the bullet and have retrained. I do generally try and avoid using the mouse in Sublime Text. I can see how using HJK and L keys instead of the arrow keys (with some prefix I assume) in Vim makes sense. Some of these tips would apply to any editor https://www.youtube.com/watch?v=SkdrYWhh-8s
Despite getting my Word Processing qualifications at secondary school and having a touch typing speed of about 60wpm I know that my coding speed has plateaued. Studies have shown that we only learn to go as fast as feel we nee d to. I would like to take a step back and re-evaluate how to reduce duplicated effort and eliminate using the mouse entirely (I do occasionally fall back to it).
