I don't know anything about Palette but have some of the Designer's Gallery programs, I've found them to be very user friendly.
I've got Studio Plus, great way to store and categorize designs (your collection will grow by leaps and bounds). ColorWorks came with it. I love Studio, it came with my Ellageo BLL so I've been organized from the start. I'd like to upgrade to the newest program, and will eventually.
I've got other Designer's Gallery programs, and they are user friendly, great programs but I prefer Embird, you can get the whole program and all it's plug-ins for about the cost of one Designer's Gallery program.
Do you want to edit? Create lettering? Thinking of digitizing?
Designer's Gallery and most other embroidery software have free trials, try them out and see what works for you. There are some free digitizing programs out there too.
This is just my opinion, I'm sure you'll you'll get others.
