I have used both Standard and the Clear type. IMO the Powertoy is better. It allows you to fine tune the settings to best fit the indivual. Since my eyes are not perfect the powertoy actually makes the fotn clear without my contacts in. So i can sit confortably at my PC without my contacts in and see the LCD clearly.
But this is all just personal preference as are most things PC related. For me it helps. While others obviously dont like what it does.
