PC Mover – Any Thoughts?

I’m thinking of buying a new laptop with Windows 10. I’ll need to buy a PC Mover to transfer everything from my desktop (Windows 7) to my new laptop.

Does anyone have any thoughts about which PC Mover I should purchase? I’d really appreciate any input you might share. BTW, I’m assuming EVERYTHING will get transferred like photos, downloads, files, WORD docs. Also, is it difficult (involved) make the transfer? Thank you.
