user58769: I was looking at two Bitcoin wallets, Coinomi and Edge.
When setting the same custom fee for both, I see a difference in the final fee reported. 
As an example, Edge wallet shows a fee of $3.13 (at 200 sats/Byte), while Coinomi shows $4.85.
I'm using the same destination address and amount for both.
Can someone explain this difference in fee?
Will the higher price Coinomi transaction be confirmed in fewer blocks? 
Have you come across this before?
Thanks.

user5406: Given that you are looking at two different wallets on two different pieces of software, the transactions that the wallets are proposing are different:

they may be using a different count of inputs
one may be using segwit inputs while the other uses non-segwit
one might be a multisig wallet while the other is single-sig 
one of them might be able to avoid a change output, while the other doesn't

This will cause the two transactions to have a differing size. Lastly, the two wallets may be using different price sources to translate it to dollars.
As the transactions' priority is determined by their fee rate, both of these transactions are equivalently prioritized at 200 sat/B. The size difference is unlikely to make a big difference for block inclusion.

user106236: Adding to Murch's response and comments, Coinomi does have UTXO control where you can set individual UTXOs as "do not spend" and indirectly control which ones will be used on your transaction. Number and type of inputs in a transaction is one parameters that influence the transaction size (and thus the fees) the most.
Unless you change a privacy option in Coinomi's settings, all change of your transactions is sent to a bech32 address. This contributes to smaller transactions. If you are having higher fees with Coinomi, most likely you have a larger number of small UTXOs, causing the final transaction size to be larger.
Full coin control at the time of sending is a feature planned for the future. Details for how to manage UTXOs in Coinomi can be found here: https://coinomi.freshdesk.com/support/solutions/articles/29000030928-managing-your-utxos
