If I were to only use only one wallet (for mobile), which one of these do you guys recommend?
I am currently using Electrum wallet for mobile and I notice that the transaction fee to send bitcoin is really high. For normal speed (within 5 blocks) it cost 0.0023 btc/kb. Even if I push my slider to the most left (within 25 block) it is 0.0017 btc/kb which is really high in my opinion.
Is it just me or does everyone see the same fee?
Should I change to mycelium because of the high fees by Electrum?
If Electrum doesn't let you choose a lower fee for your transaction, move to Mycelium. They don't let you "fully" customize your fees but it's still better than the 10 fee options Electrum let you manually choose for your fees.
Just keep in mind that Mycelium is also not the best wallet for custom fees, since you can't write the exactly fee you want to pay. Looking at my Mycelium wallet right now, looks like the lowest fee I can choose for my transactions is 0, 1, 22 and 44 sat/byte - which should be enought to save some money but don't stuck your transaction forever.
