What is the best wallet for Bitcoin?

This is my first post, so please be kind. Future posts will range from cryptocurrency to Oriental Medicine to religion and philosophy to investing . . . Some will be what I have learnt over the years and some will be asking questions.

I have recently returned to the cryptocurrency marketplace and have been looking over the options regarding where to store my bitcoin and other crypto's For this article, I will just address the bitcoin wallets and we can discuss the other currencies at another time. Just to let you know upfront, I will not be telling you what is best. I will just be addressing issues that I see in choosing and am even asking for advice based on some of the functions I am looking for.
I am dealing with small amounts of bitcoin at this point and have been looking at coinbase, uphold, Jaxx, bitpay, electrum, blockchain and exodus for a start and here are my issues with different wallets.

1. I would like a wallet where I can use my Fiat currency to buy directly in the wallet. In my case, it is in US Dollars. This feature is available in coinbase and uphold. (Blockchain only links in Europe)
2. I would like a wallet to be able to hold small transactions without penalty. This way I can make regular small deposits from Genesis Mining or other mining operations without penalty. As an example, Bitpay Treats each deposit as a separate transaction, so when I try to use my BTC, the fees sometimes make the transaction impossible or the fee becomes ridiculous.
3. I want my wallet to be able to work on my desktop and on my android. This eliminates exodus. If I use an exchange, exchanges like poloniex require 3rd party apps on the android and I am not sure which ones I can trust there.
4. Anonymity would be nice but conflicts with my next feature I would like.
5. an attached credit card would be nice. Currently, bitpay has this (but I do not like that I can access many of the deposits because of the way they handle them) and coinbase has the Shift Card that attaches to the account.
6. Lets not forget security . . .

These are issues with a wallet that I think everyone has to at least be aware of. Some will be more important to you than others and some fo the issues I have listed might be insignificant to some of you also.
I would love to hear your thoughts on this to help me decide which wallet or wallets would work best for you and me.
