The Touch Pro 2 is a WM device and 528Mhz processor IS in fact slow for a WM device compared to other new offerings like:
However it seems like you'd prefer physical QWERTY keypad. In that case you should go with the Bold 2.
There's also the Pre which offers touch and type. However, not sure what your carrier limitations are if any.
So to answer your question Bold 2 vs Touch Pro 2... I'd say Bold 2 esp because your current device is a BlackBerry.
