Please help me to find the best everday bag

I agree with others it depends on your needs and likes.

For me, I need medium-large, strong, light-ish in a neutral colour and preferably not shoulder (I can get terrible shoulder ache) but either a cross body soft hobo style or a more structured had-held. Huge logos or monogram fabrics are not for me everyday either - sometimes I like to 'disappear' and be the only one around who knows what I am carrying. The leather or fabric would have to be relatively low maintainance too so it helps to know how different leathers behave longterm and in certain weathers.
