best spoofing method for android?

so, are you spoofing on your main account? or just an alt?

if you only spoof on an alt, how do you plan to get perfect pokemon on your main account?

I got that nothing is safe. but a root phone is a safer way to spoof than a non-root phone, correct?

for android, specifically for phone with android 9, which software is best for spoofing?

thanks
