Need someone to look at my Rebel and Imperial lists

By Father Bloodlust, in Star Wars: Armada Fleet Builds

I've just gotten into Star Wars: Armada (only have the core set), and after a couple of games in which I've played both Rebels and Imperials, I'm kind of paralyzed by indecision as far as which faction to go with. Both of them have their strengths (naturally), and I'm wondering if any of the lists I've come up with would do any good in an actual game.

So here's the two lists I've come up with. Both are constructed with tournaments in mind (400 points).

First is the Imperial list, which is intended to be an "overwhelming force" sort of list. I want the Gladiators to flank the Imperial so that any ships approaching will have to go under the guns of at least one Gladiator.

-Imperial II-class Star Destroyer (120)

--Title: Avenger (5)

--Commander: Darth Vader (36)

--Ion Cannons: Overload Pulse (8)

--Turbolasers: Enhanced Armament (10)

--Weapons Team: Gunnery Team (7)

-Gladiator I-class Star Destroyer (56)

--Title: Demolisher (10)

--Weapons Team: Ordnance Experts (4)

-Gladiator I-class Star Destroyer (56)

--Title: Insidious (3)

--Weapons Team: Ordnance Experts (4)

-TIE Fighter Squadrons (10) (80)

Total: 399 Points

Second is the Rebel list, which is intended to be a light fleet. The idea here is that the Nebulon-Bs attack from the front, using their XI7 turbolasers to do some damage, with the X-Wings providing support, and the Corvettes perform a flanking run, taking a turn or two to angle themselves towards the target's rear area and combine their firepower.

-Nebulon-B Escort Frigate (57)

--Title: Yavaris (5)

--Commander: Mon Mothma (30)

--Turbolasers: XI7 Turbolasers (6)

-Nebulon-B Escort Frigate (57)

--Title: Salvation (7)

--Turbolasers: XI7 Turbolasers (6)

-CR90 Corvette A (44)

-CR90 Corvette A (44)

-CR90 Corvette A (44)

-CR90 Corvette A (44)

-X-Wing Squadrons (4) (52)

Total: 396 Points

So am I onto something here with either list? Could either of them stand a chance in an actual tournament?
