Question Ranking
Pros
Pro Blazing fast rendering with GPU-accelerated
Written in Rust with a philosophy focusing on speed and simplicity, Alacritty is one of the fastest terminal emulators out there.
Pro Looks good
Alacritty looks very slick on Linux, especially with GNOME or i3.
Pro Simple configuration
The configuration file is very well made and easy to use. You can fine tune your preferences to perfection in a matter of minutes.
Pro Comprehensive font options
Alacritty can be configured to adjust line spacing (height), letter spacing (width), and individual character horizontal/vertical positions.
Pro Has support for image previews in w3m and ranger
Pro Has text ref-low when window is resized
Pro Fast and simple but with true color support
It's simple and fast like xterm or urxvt but with truecolor support which is a big plus if you use a terminal based code editor. Basically Alacritty has all the features you need and nothing you don't (if you're using tmux for multiplexing).
Pro Supports multiple windows, tabs, splits/panes
tmux-like functionality with native UI even on Windows systems allows managing multiple terminal sessions how you like.
Pro Looks good
Highly customizable appearance and comes with over 240 built-in color schemes.
Pro Open Source and Free
Pro Supports font ligatures and stylistic sets
Ships with JetBrains Mono, a modern programmers font, so that you can enjoy modern typographical features such as contextual ligatures and font variations/stylistic sets in your terminal environment.
Pro GPU Accelerated
Cons
Con Cannot into ligatures
Alacritty does not support ligatures in Fira Code, Iosevka etc.
Con Unreliable Font Rendering
Like a box of chocolate you never know what you're going to get.
Con Sacrifices basic features for raw performance
The Suzuki GSXR of terminals. Or your ditzy, blonde high school cheerleader; fast and pretty but not a lot going on under the hood.
Eschews a negative developmental philosophy towards including said functionality, with the official reason cited in project documentation as "Not within the realm of a terminal emulator" and ostensibly, "best left up to other tools such as terminal multiplexers" [such as screen or tmux]. Which is unfortunate when you factor in speed against terminal with the functionality built in vs their reliance on 3rd party tools:
tmux on alacritty: 'find /usr' time: 3.234s, cpu: 72%
tmux on konsole: find /usr' time: 1.777s, cpu: 96%
See issue here.
Con Lua learning curve for config
The only reason it would be difficult to recommend is that it's for experienced programmers.
