There are many videos on You Tube that show the differences between DAWs and what may be the easiest to use for you. (There is no one size fits all)
Most DAWs also have trial versions available so you can find one that suits you before purchase. (I've always liked Cubase)
If you are Mac user, then the free Garage band will probably be all that you need. (If you want a new computer and would like to get into Mac, then the new Mac Mini is fantastic value. (Just make sure you get the 512GB storage version)
When it comes to editing Midi (Or audio) there is no substitute for a big screen.
