Like Tails says, good luck trying to catch a Lala. Pretty much impossible if you're not in a D-9, Typhoon, or a same Lala. At least Typhs can be caught if he runs dry of WEP during the next 5 mins.
Also, like Flyboy says, the La-7 is so much easier to handle that more sucky pilots fly it - hence, more mistakes made, more opportunities to slap it silly.
However, Typh pilots are usually the most timid of the timid. Excellent SA.. very cautious and edgy.. not exactly the fun type to be around, and not easily caught, unless you plan an ambush, and jump him with a La-7 or a D-9 with alt advantage.
Dangerous? Oh yes, the Typhs are more dangerous. But only because the average Typh pilot is so much more dangerous than the typical Lala pilot.
