the one thing linux really hasnt been made on par with winblows yet is the dreadful amount of options for android simulation -the most popular choice seems to be Waydroid, but its such an unneeded hassle to set up at all -genymotion is just slow -and than you have things like android x86 which entirely defeat the point of an emulator
Do you mean emulators such as the Android emulator that comes with Android Studio, or is the latter lacking features that other software on windows possess?
android studio is painfully slow and has not exactly a friendly userinterface (its been a couple of years)
The emulator inside Android studio is a separate binary. If you use Android studio like a heavy weight software update tool, you should see near native performance if you just launch the emulator on its own.
