Zoom is harder than reg tables, winrates are lower than reg tables, the only plus about zoom is really the easy to start a session and the increased volume.
If we are talking about 2nl then can say i can beat both, but on reg tables i can get twice the winrate, i got 12bb/100 on reg tables where on zoom ended with 6bb/100.
But yeah both are beateable, just need to start geting hands on zoom regs to see ranges, still fish but less than regulars and zoom is really a setmine field/nuts game.
I never face so much set vs set situations on reg tables like you face on zoom.
After playing zoom try regular tables and going to feel games are lol softer, but also lol slow
