we need to design a wein bridge oscillator, with an output frequency of 800khz and Vp 0f 10V.. can anyone suggest for the best op amp to use in the design

Pretty high requirements (bandwidth and slew rate).
Most probably, a current-feedback amplifier (CFA) with a bandwidth of several 10th of MHz will be necessary.
For current-feedback amplifiers, the feedback resistor Rf determines stability and optimum performance.
For a gain of +3 the optimum value is approx. Rf=500...1000 ohms (see data sheet).
Thus, I recommend to change all resistors in the feedback path to corresponding lower values.
It is to be expected that, in this case, theoretical and practical values will come much closer.
