Pro Dynamically resize window
You can change the width and height of the console window without having to reset your session.
Pro Supports fullscreen mode

Pro Can run any existing shell
Console2 facilitates the running of CMD, PowerShell, Cygwin, PuTTY, etc.
Pro Free and open source
Console2 is licensed under MPL 1.1/GPL 2.0/LGPL 2.1, making it free and open source.
Pro Tabbed
Console2 allows the user to create tabs for separate instances of the terminal, allowing them to have both multiple shells and multiple instances of the same shell open.
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).
Cons
Con Not maintained
The development of Console2 has been abandoned. The latest change was made in 2013.
Con Stopping a script closes the tab
Usually when a script is running and you try to stop it with Ctrl-c, it stops and shows the empty command prompt waiting to get a new command. In Console2 this does not happen: instead the whole tab where the script is running is closed.
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%
