I've never owned a Technics, but I do think the Otari is a better bet. I have the Otari (model MX5050 BII-2) that graced many a radio station and small studio. That was the target market, while the Technics was mainly for home use. The Otari is a really tough, rugged machine and will do everything you want in a deck, plus it sounds great, far better than the Teac X1000R it replaced in my system. And as a recording deck I think it's hard to beat.
By all means, whatever you decide, go for it. The world needs more tape fans :-)
