It all depends what you want your tank to do! Your HL will happily Pootle about indoors and on light terrain. People seem to think the rx18 to be a decent ESC (IMO I think it's rather jerky and doesn't help handling on grass). Although this does seem to be when used in combination with a DBC and hobby radio, but then with that the price is already rising. For more serious work I still think the SLU offers the best value for money as it provides a fantastic ESC great sound and is very flexiable for battling as it can be programmed via the remote control which is supplied. The battle system, speaker and LEDs are all supplied too.
Not sure if there is a typo in that sentence, but to be clear an RX18 when mated to a DBC2 with the momentum, and a good gearbox handles fine. The difference between it an a Tamiya system is unnoticeable.
Quite frankly there is enough difference in each system that to say one is better then the other is subjective at best. Each one offers something different. EL MOD, Beier and Benedini offer programmable sound so one system can be used in multiple tanks. You just need to spend 5 minutes altering the sound file, and what was once a Sherman is now a Tiger. The fact that these systems can be moved around in different tanks can if fact save you money over having to buy a unit for each tank. Look at your work bench and count the dollars of sound systems sitting in tanks, making no sound!!!!. SO again value of these system depends on your needs, and the opinion about that value is very subjective.
JUst like some are quite happy with the HL IR system for their needs. So the Beier sound system that fits to HL tanks would give these users great sounding tanks with the HL IR system. A lot would claim that is the best value. TOO bad Heng Long never used the same frequency the Tamiya uses, and then these HL users could use their factory tanks against Tamiya without having to purchase anything
