I like Pigtronix Infinity Looper the most because it works very well in live performances, but it is not a suitable option for beginners. I think you can go with TC Electronic Ditto Looper because it is a worthy choice for newbies. I recently read its review from here https://www.happynewguitarday.com/best-looper-pedal/ and found that its swift double-tap, uncompressed 24-bit audio processing and other simple features are very attractive for newbies. But its size is small, and you should think about your requirements before buying it.
In the same token, Boss RC-1 is also an ideal choice for beginners. Its design is very simple, and you can use it for 2 hours of recording as well. Hopefully, you will pick the right option.
