For Excal, with or without EB, I'm going to say Naramon. Here's why:

1) A good EB build is (almost always) going to be based on a Berserker-based melee weapon.  Increasing melee crit chance (and damage) - especially if used with a melee with crit damage of 2.5x or more - is going to increase damage far more than 20% more base damage, and increasing crit chance will build your Berserker stacks that much faster.

2) While finishers aren't the same thing as stealth kills, I believe you can nevertheless execute stealth kills if you manage to pop Radial Blind before you alert a room, you should be able to get stealth multipliers anyway.  I am not certain about this, but I think that's how this works.  Naramon can provide you with free cloaking to keep this going.

3) Naramon is also going to increase affinity gained from melee kills - which includes EB, even kills made with the energy waves.  This, in turn, increases the amount of affinity that can be channeled back into focus.  And because the kills are scored by a warframe ability, 100% of the affinity goes to whatever Excal's focus is, instead of being split between Excal himself and the focus on his weapon.

So...I'd go with Naramon. Even if you decide to switch to Madurai, Naramon is better to start with because of #3.
