I recently found out that my wallet Multibit HD 0.4.1 is considered as buggy and in some cases all Bitcoins stored in it can be lost.
I hadn't heard this about MultiBit. Are you sure you heard this from a reliable source? Can you link to where this has been demonstrated?
So i did some research and found out more about wallets. I saw only two of the main wallets download the whole network (full bitcoin Client) Source:

Make sure you have a few hundred gigabytes of storage space available to run it. Also be aware that after initial install it will take a while to synchronize (anywhere from a few hours to several days depending on your computer system). Most importantly, make sure you create a backup of your wallet after you install it (and any time you change your password) and store it in a safe place.
Now my question is:
Shall i chose Bitcoin Core or Bitcoin Knots ? It says Bitcoin knots has more features but not as well tested.
Someone has experience with these two wallets and can recommend something, with a statement why he recommends?
You may also want to consider Bitcoin Unlimited. It is currently compatible with Bitcoin Core. If, in the future, there is a decision to allow larger blocks in the blockchain, Bitcoin Unlimited is already ready to accept them.
