Aight, here's what We'll do...a side by side comparison...and what the heck...I'll even do the GPS tracker...
First here's the Hornet 554T\
Introducing the Hornet 554T 2-Way Remote Start/Security System. A state-of-the-art FCC-Legal 2-Way system that leaves the competition in the dust!
Smaller is Better!
The Hornet 2-Way doesn't take up much room in your pocket, and the in-vehicle antenna doesn't take up much room in your windshield.
Excellent Range!
The Hornet 2-Way should get similar range to other superheterodyne systems: over 1,000 feet under optimum conditions.
Cool Blue E-L Backlighting!
Nobody does Electro-luminescence like Hornet. You'll love it in the dark!
Learns Directed transmitters!
The 554T can learn up to 4 transmitters, and it comes with one 2-Way and one regular 4-button remote.
Time/Temp via Remote, including Parking Meter Timer!
Read the time on your 2-Way just like a cell phone, and remotely sense the temperature in your vehicle. Too hot or too cold? Time for remote start!
And I believe it uses the 553T for the majority of the Security features, and those would be:
The all-in-one Hornet 553T is just right for someone looking for convenience and security. With this system, the convenience of remote start and the assurance of a protected vehicle are available with the push of a button.Pre-warm your car in the winter, and pre-cool it in the summer with the top-of-the-line Hornet 553T remote start security system.

Well the first thing I noticed is that the Hornet has a cool little backlit screen...and the Viper doesn't...Big Deal...
Other things..the Viper is more expandable than the Hornet, and has more channels...but that is also fixable, with a DEI Part, that turns one channel into 3. and yada yada yada. Basically... whatever the Viper has that the Hornet doesn't can be added on, using some sort of DEI part. It just comes down to one thing $$$$$. Me personally I'd go with the Viper jsut to take out the hassle of having to get expander modules and such. But I'm also lucky enough to have a friend that owns a shop, so my warranty won't be voided
Here's what I'd do....if you feel confident enough to install an alarm yourself...get the Hornet..they're basically the same alarm with a different name, only difference is, that the viper has more channels, and costs more for the few features. Now if you dont' feel confident get the Viper, and have it installed....That's what I'd do..
