Any key cap is good for typing and, by extension, for any use involving it, name it gaming. However the efficiency for the task may vary, but it is more related with the practice the typist have with a particular key board, including all its elements, key caps, switches, material and its texture and layout. Focus on the key cap type only and making an argument just based on it regarding a typing experience is not a good scientific approach. Some people find rubber domes very good for their use and you can see them typing very efficiently on them, that alone demonstrates that there is no a particular key cap, or even a key board, mechanical or not, that may be the best for certain computing activity involving typing. In the other hand, preferences will be very different for each individual and testimonies shared here cannot be generalized. Some others, find lap top key boards to be very nice to type on, again, it may be a matter of continuous use of them that make their use very friendly.
For the OP, if you want to know how does DSA feel, then do you homework and give it a try and make your mind about it, but you should be aware that the final feeling is a result of more than one factor and that it may be different from some others experiences.
