Not possible to make comparisons to the 77 fire in Singapore and this incident. Comparing oranges to clementines ...
Good decision made in this case, but my generally feeling is any fire - get the pax off. It was contained quiet quickly.
Having said that , in reference to Singapore the fire crew stated over the headset to the cockpit, "they will have the fire under control shortly" I am not entirely sure i would be content on hearing this comment , you have to ask yourself, what if the fire becomes out of control or a fire tender becomes unserviceable in the process.....Judgement !
