Is there a specific reason you're going with a plant protein vs whey? ie. vegetarian or money? This will control your options.
In terms of protein, not all protein is the same. There's something called bioavailability that is a big factor. Just because they have the same protein doesn't mean that your body processes/uses all of that protein. Pea protein is in the 60% range. Whey is in the 90% range. This means even though the overall protein is comparible between a scoop of either. You have to eat more pea protein to get the same benefit as Whey.
So monetary and performancewise, I don't think any single plant protein compares with Whey overall. However, if you're a vegetarian and don't want to take any animal based product, you'll have to either revisit your beliefs or take the plant protein and adjust to deal with the differences.
Say you go pea protein and want to meet your 50gram protein goal in the morning. Pea protein is around 84% protein. So at a base, you need around 65 grams of pea powder to meet the overall goal of 50 grams protein (roughly same as Whey). However, Add on another 30% (to cover the 30% difference in bioavailability) and you're at 84 grams of pea powder to meet your goal in the morning.
Pretty big chunk of powder in the morning (might want to break in half doses). Monetarily speaking, you're spending more for the pea protein because you have to use more (even if the jar is cheaper). Vegetarian speaking, you'll meet your beliefs, just realize they're not totally compatible with how your body actually works.
Incidentally, neither Whey or Pea powders would be considered Paleo.
