Please help me understand the various fluoride percentages in toothpaste, and find the highest level of fluoride in over-the-counter paste.

I'm looking for the highest level of fluoride in over-the-counter toothpaste, and I don't understand how to compare them based on what's written on the package. For example, here's what's written on four different tubes:
- Crest Pro-Health: Stannous fluoride 0.454% (0.16 w/v fluoride ion)
- Crest: Sodium fluoride 0.243% (0.15% w/v fluoride ion)
- Sensodyne: Sodium fluoride (0.15% w/v fluoride ion)
- Colgate Pro Clinical: Sodium monofluorophosphate 1.14% (0.20% w/v fluoride ion)
Is one type of fluoride stronger than another? If I'm looking for the most fluoride, do I compare the percentages of (for example) stannous fluoride with sodium fluoride? Or do I compare the w/v fluoride ion percentages?
The last one I listed -- Colgate Pro Clinical -- was the highest fluoride content I could find (I think!). It's not for sale in stores anymore and not listed on their website. I think they've discontinued it and that the ones I see online are old stock. What is the highest level of fluoride I can find in toothpaste today? (I know about prescription toothpaste, gels, and rinses. I'm only looking for over-the-counter toothpaste.)
