OP6 for $100 off or wait for 6t McLaren?

I just saw that the OP6 is back in stock with the $100 off. It's tempting, but I'm also tempted by the new 6t McLaren.

Things I care about in deciding:

• Speed and snappiness (6tM wins here)

• Quick updates (6tM will last longer)

• Price (OP6 win)

Is the price difference worth it?
