This Wikipedia article is worth reading Complete protein. In particular, this quote:
"In fact, the highest PDCAAS scores are not given to commonly eaten meat products, but rather to animal-derived vegetarian foods like milk and eggs and the vegan food soy protein isolate."
So, there is one answer for you: Soy protein isolate.
Another point is that many plant based protein sources may be low in some essential amino acids and hence not good meat substitutes by themselves but certain combinations may be much better. A real case of the whole is greater than the sum of the parts. This is discussed in this Wikipedia article Protein combining.
It used to be recommended to do this combining within a meal but that recommendation is now relaxed. That article does not give an alternative guideline. I thought that I had seen a day. I will try to find and add a reference.
The protein combining article gives an example that rice alone as a protein source may lead to a protein deficiency but combining it with a legume can solve that. Convenient for me as rice and beans is a favourite meal.
Finally, a measure that I have only just noticed and deserves some more research is protein per calorie. Some plant sources are better in this sense than meat. I will try to find and add some references.
