Obviously. My interpretation is that the two GUI designers, that of

It's not about what the GUI designers manage. In both cases, they work
with completely different frameworks. If you use the LCL, you are
working with LCL controls (TWinControl etc.) no matter what
backend/widgetset is used. You will always work directly with the LCL
which essentially is "just" another abstraction layer.
If you use the fpGUI Designer, you work with fpGUI as framework. In
that particular case, you directly interact with the fpGUI controls,
something you don't do when working with the LCL.
I understand that the different provenience of the two "legacy" GUI
designers can/needs to be handled when integrating fpGUI into
Lazarus.
And I feel that "in the end" both should result in a similar level of
perfection. This might mean that a rather large integration of them
could be desirable.
Eventually the LCL only uses widgetsets as a means to an end. It uses
widgets from a widgetset to build its own controls. That may be by
completely integrating a certain widget or by using other means,
depending on what a specific widgetset offers (for example a TLabel
could be a real widget on GTK and maybe owner drawn on Win32). It may
also be, that a widgetset provides for example a TreeView that could be
used to realize TTreeView, but doesn't offer all the features necessary
so you still end up building it from a bunch of simpler widgets and
owner drawing.
So no, in the end you have two completely different results/goals
depending on what framework you use: fpGUI or LCL - no matter if the
widgetset you choose is fpGUI again. You will still end up with
different controls, different structure and different functionality.
