Bottom line
Per 100 g, Portabella Mushroom provides 32 kcal, 2.8 g protein and 4.7 g carbohydrate; Shiitake Mushroom provides 44 kcal, 2.4 g protein and 8.2 g carbohydrate.
That is a difference of 12 kcal per 100 g — small next to what the cooking method adds.
Portabella is a mature crimini — large, meaty, the one that stands in for a burger patty. Shiitake is a different species with a stronger, savoury flavour and woody stems that are worth saving for stock rather than eating. Shiitake carries more carbohydrate; portabella more water.
In short: portabella is the lighter option per 100 g, but with vegetables the choice is usually about texture and how they cook, not calories.
