Against major opponents such as SENAI, let’s look at stats for the three A/R in discussion:
Jadeja - Bat Avg 31.9, Bowl Avg 25
Shakib - Bat Avg 32.5, Bowl Avg 31
Stokes - Bat Avg 35, Bowl Avg 35

The stats against top opponents is the best illustration of who is the better player of the three. It clearly indicates that Jadeja is well ahead of Shakib and Stokes as bowler and only slightly behind them as batter. While he may not have a double hundred like Stokes or Shakib, he does have a 175* to boost for. He could have continued batting and hit a double ton if wanted. Jadeja is comfortably a better test A/R than both Stokes and Shakib.
