Record Type / Editable Grid which one is better when we have 100 Columns.

I need to build an interface with 100 Editable Columns and all the columns need to be searchable & editable.
(Like a table with 100 columns and we should be able to input something and search / modify the data and submit to DB).
Which approach is suitable for this requirement? Should i go with Record Type / Editable Grid.
(I am aware that the performance may be slow due to 100 columns. But business want to evaluate how it looks like and see the performance)
