That's true, it's about 26% cheaper to use segwit, but is it worth? Check mempool.space to see blocks are not full, you're able to send transaction for the minimum amount. There is something shady with all these types of addresses, that's why I'm asking if it's not more important the security of your coins compared with a 26% fee eficiency.
Electrum does a good job both mobile and desktop version, it does not give you the option to generate uncompressed addresses but you can import and use them without any problems. For long term storage I use coinb.in on an offline phone to generate addresses, sign and build transactions.
