Ledger Nano X has many issues faced by the people like the battery not being charged properly and some other bugs which have let the people change it so wanted to ask has you faced any such issue in the wallet?
I've had that model for several years and I haven't had any problems, and I think that most of those who bought it back then didn't have any problems - although I remember one of our members who even then had problems with the battery, which discharged very quickly.
....the best one are Ledger and Nano but depends on the coins you want to hold in your walllets.
I assume you wanted to write Ledger Nano, because Ledger is a company that produces (or has produced) models called Nano S, X, and S Plus. All three models should have support for the same coins, at least that was the case for S and X, and I doubt that S Plus has something that the previous two models do not have in terms of additional support for some new coin. The difference is in the internal storage, which only allows you to have more coins apps at the same time on X and S Plus than on S.
