So . . . this may be way late tot he game, but I notice nobody seemed to bring up the good advancement avenues for Adepts through Qi Foci and Weapon Foci.
For example, you pointed out the effective cost difference between a Sammy with WR 2, and an Adept with Improved Reflexes 3. Keep in mind, with a Qi Focus 4 (Improved Reflexes), you only need to spend 2.5 Power Points to get IR 3. Add to that the dicepool differences - Both could max out Blades with a specialization and high agility for a base pool of 14/15. The Sammy could boost that with Muscle Replacement or Muscle Toner for the agility, but the Adept could do the same with a slight essence hit and money for the Toner or with Improved Physical Attribute; they can also augment their Skill with powerpoints, then add bonus die from a Weapon Focus. For melee combat, seems like they're streets ahead. Purchasing/bonding cost for Qi Foci are surprisingly decent, too.
