Both would be better options in some circumstances, such as with a slightly raised PSA suggesting a small tumour that could be missed. However, in your case it is rather academic and so it would seem odd to subject you to an unnecessary general anaesthetic.
Why not wait to see which order the hospital appointments are offered to you. If they give you an MRI or mpMRI first and the results are equivocal, a normal biopsy is fine. I don't think it will apply in your case but sometimes the results of the MRI and bone scan are so clear that they don't bother doing a biopsy at all - no point in subjecting the patient to additional risk.
