GG06 and MH71 have wider toe box, so it fits 'normal'. TG73/DG70/Deco have narrow toe box, so it will be very tight at the toe area if GG06/MH71 fits you fine; order a width up if needed (not length up).
p.s., if GG06/MH71 fits you fine, TG73/DG70 will most likely to be too narrow at the toe box, and vice versa. There's no reason to own both the wider toe box and the narrow toe box lasts since the fit will be exclusive at the same size/width.
For my feet, its the Deco last which has the narrower toe box area compared to the GG06/DG70/MH71/TG73 (these four have the same toe box room)
The design of the shoe ALSO contributes to the overall room throughout the shoe and toe box...which might explain why others report a better fit in a 1/2 size larger TG73 lasted shoe compared to a shoe with the MH71 or GG06.
For example, I have the new faux laced balmoral lazyman in the TG73 in 11.5...yet have another GG lazyman shoe with the TG73 in 12. I had ordered the balmoral lazyman in 12, yet it was too big...so I had it relasted
