8" JL vs 8" Eclipse

Hi, I am currently downgrading my system and was wanting to get 1 8" for the trunk. I was originally thinking of getting a JL setup going, but then came across a good deal on some eclipse equipment. Dont necessarily have a preference, just would like whichever is a better sub. I mainly listen to techno and rap, but want it to play everything well. I like the sub to hit low.
Which would be louder / boomier, which would have better SQ?
I would expect the jl to be boomier, with less sq, but would the sq still be good, just not As good as the eclipse?
Here are some specs

Eclipse

Power Handling: 300w continuous / 600 Peak
XMAX (one way): 0.73" / 18.5mm
Impedence: 4 ohm SVC
Fs: 40Hz
Qts: 0.57
Vas: 0.26 Cuft
Rec. Enclosure: 0.3cuft sealed
Mounting Depth: 4.5"

thats all the specs i can get my hands on for the eclipse. dont have the model number, an educated guess would be 87081.4, but not for certain. I am trying to look into if this sub is ok to be in a ported enclosure and what size, but if I cant find anything it might have to be in a sealed box.

JL

Free Air Resonance (Fs): 35.14 Hz
Electrical “Q” (Qes): 0.501
Mechanical “Q” (Qms): 7.071
Total Speaker “Q” (Qts): 0.467
Equivalent Compliance (Vas): 0.54 cu. ft. / 15.29 liters
One-Way, Linear Excursion (Xmax)*: 0.375 in. / 10.0 mm
Reference Efficiency (no): 0.127%
Efficiency (1W/1m)**: 83.24 dB SPL
Effective Piston Area (Sd): 32.02 sq. in. / 0.021 sq. m.
DC Resistance (Re): 3.77 ohm
Nominal Impedance (Znom): 4 ohm
Thermal Power Handling (Pt): 250W
Driver Displacement: 0.03 cu. ft. / 0.85 liters
Net Weight: 8.2 lbs. / 3.7 kg

the jl can be put into a ported box at .35 cu ft. So, what do you guys think of these subs, do they sound good for 8's, 1 better than the other? Would only being able to put the eclipse in a sealed box automatically make the jl the better option, or does it not make too big of difference?

 

lets say hypothetically they are both in the ideal box
