may i ask why don't you want to use Electrum? was there any particular problem or lack of feature that made you decide that?
in any case, you can visit
https://bitcoin.org/en/choose-your-wallet and see the alternatives. click on the platform you want to use the wallet on and then click on each wallet to see the details.
Multibit-HD is another SPV wallet which people usually go to.
Bither seems to be another SPV wallet but i have no idea how it works.
I heard many times about multibit-hd but is it lite weight or you still need to download the whole blockchain?
Electrum is the go to wallet right now as the dynamic fee calculator is very good and you can always use RBF to send replaceable, not to mention hardware wallet integration with Trezor and Nano S. The Android app is just as good but without hardware wallet support.
Yeah your right dynamic is really good but when setting for instant to slow almost highest fee that i seen right now .. unlike before that the maximum is 50k satoshi if you can seen the dynamic today they are asking for 0..001 or above.
So that is why i am looking for other wallet which is has similarity for electrum because electrum is one of the good wallet never had any problem but the fee is very high..
let me ask about the trezor if you still need to download the whole blockchain?
Never heard about nano S. but i'll check the official page.
