Both are probably more expensive than the upcoming R&T solution, but both are also likely higher performance for track work and competition applications.
Although both of those Ohlins based systems are excellent for track use on track or competition 1M/M3's, they are not recommended for street duty at all and will likely not carry any warranty.
For street duty and track days, Road & Track will be perfect and nearly half of the price.
