Definatly two extreems in their ways.
The Locust is a fun little mech. Fast, though not to the more modern standard of blistering hyper speed, so its still a bit on the vulnerable side against the most modern mechs and depends on plenty of cover. The up side is that, especaly in very close, it's armed to the teeth. The MPL is a very solid weapon for harassing on fast passes or hunting other fast lights, but the real show is the eight ERSLs, which combine with the medium for a potental 47 damage. Sure, the sweet spot is two hexes out (at point blank, you risk physicals, which is a bad idea in a 25 tonner) but if you can get behind some fool, you can really light him up.
Plus, its a Mongoose mech, so its one of the three or four best units in the game just for that.
The Python has a lot of accuracy, but in my mind it can, if you're bold be a bit of a team player. At 75 tons, it can afford not to jump and just take very accurate shots. Against faster mechs (like that Locust) it will honestly tend to do as much damage as a Dire Wolf since it won't ever miss, which frees the actual Dire Wolves to shoot big slow sons of bitches that they can't hardly miss. Even compaired to average sorts of Timber Wolves and Summoners, against anything more manuverable than an Annihlator the high accuracy means that expected damage will be about the same; I'd rather hit with both LPLs than just one of a Timby A's PPCs, weather against a Phoenix Hawk or a Battlemaster (at range). Many people look at the larger Python like they do the Wraith or Vapor Eagle or Piriah B and try and jump and dodge fire, but its a big enough mech that so long as you can keep the range open (something large battles are great for) you can stand in a slugging match with any but the best heavies and have more than a little hope.
Of course, as a dualist where you can lean on thouse jets a bit, its the equal of all but the greatest assualts. TCed LPLs are scorned for a very good reason, and the derision that the Black Python gets so often is because it really is that solid a mech (even with the funky design choices).
