Easy. The Raven 3L can mount ECM, which makes it more difficult to target by enemy LRMs and every mech within a 120m radius equally difficult to target with LRMs, and it can mount 2 ER Large Lasers and still move at around 150 kph, whereas the spider can only mount 1 ER Large Laser at best and cannot mount ECM/.
That's disinformation. 5D is the ECM-enabled Spider, you can have ECM in it. You can also mount 2 ERLLs in it rather easily:

The reason why I'd say the Raven is better, is because the Raven is a 35 ton mech, and Spider is 30 tons. As you can see, the 5D can do 2xERLL with ECM and a JJ (which the Raven 3L can't get), but because it's 5 tons lighter, it can't do it using the max engine, or without sacrificing considerable amounts of armor, which you can do with the 3L:

Also, the other variants for Spiders besides the 5D are honestly rubbish (can be fun to play at times, but can't call them effective), whereas the currently quirked non-ECM ravens, especially the 2X can pack serious firepower for it's size. You can have 2x PPCs in Ravens, which aren't really feasible in Spiders, but a RVN-2X with 3xLL or 2xLL + 2xML would probably be more effective at the same ranges due to quirks.
The Raven also has arguably the best hero light in the game at the moment, Huginn, if you're interested in those. It's a very brawly mech and with the 3L and 2X would likely provide the greatest variety you can get from 3 variants of the same light chassis.
I'd recommend Ravens if you want ECM and generally longer range firepower, Firestarters if you want JJs and feel you might prefer brawling, or the Spider 5D if you want both and don't mind that the other variants you get are a worthless painful grind.
Edit: My personal favorite at the moment is the Locust 1E, which with it's current quirks I'd actually claim to be one of the most powerful lights in the game. However, it's very unforgiving to play, so it's very hard to recommend as a first light mech. Also, again, most of the other Locust variants are quite bad compared to it. However, Locusts are very cheap, so if you're confident in yourself and/or don't mind dying every time you make a mistake, it could be worth looking into, too. For example, 6.7 mil (half the price of a fully upgraded max engine 3L) fully upgraded:
