Absolutely the same, no difference. Given you use clones that spoof cpu data, build props, is_emulator flag, adb_enabled flag, and development_settings_enabled flag. IG backend will see no difference in this case.
But the thing is, ridiculous as it may sound, emulators are not cheaper. They eat a lot of cpu and ram. It’s hard to run many simultaneously on PC, and cloud is actually expensive. While cheap used Android phones (even Samsung, Pixel) are around $50 per piece. With enough power in each to run smoothly on its own. Think about it!
