I am finding that even in Studio one I need additional plugins the get the kind of master I want. The plugins in SO are ok. That's what many regular SO users tell me. A lot of this is subjective. 
Most will say it is possible to get a decent master in ( take your pick of daw) with the included tools. The same people who say that don't use only the stock plugins in their masters.
 
The only real difference between SO and CbB in terms of mastering is that SO has  album assembly, track diagnostics and tag section. The plugins in SO aren't all mastering grade depending on the situation. Unless you're ok with "ok".

...I do find CW's analysis tools lacking, but when I put the final mixer/mastering album into Studio One to use its analytics, I can do a final reality check.

I think it's a fair assumption that anybody who's serious about doing their own mastering has acquired the necessary third-party analytic tools to allow you to master in whatever DAW you're comfortable with. 
 
I feel no limitations at all when mastering a CD project in Cakewalk. Well, maybe just one: if you could insert indexes and then write an iso image directly from Cakewalk, that would be pretty cool. Does Studio One do that?

Studio One's mastering page (which is functionally separate from the multitrack song page, aside from the song/project linkage that's unique to Studio One) basically replaces a program like what was Sony's CD Architect, not a program like CbB. It's an entirely different animal from mastering in a DAW; you can insert P and Q codes, export in multiple data formats, do CD-text, create disk images, and perhaps most importantly, both export and import DDP files. Not a lot of programs can import DDP data, but sometimes you'll need to edit a master's metadata.
 
Also mastering analytics are a moving target. Studio One was quick to adopt flexible LUFS metering (as well as Bob Katz's metering). By the time you've bought all the required analysis tools, you might as well just pop for SO so you can do album assembly and DDP exports.
 
However, it can't do the deep waveform surgery that a program like WaveLab or Sound Forge can do. I use those for the "tough" cases.
 
I have no problem mentioning SO here in this context, because CbB doesn't compete with SO in respect to the mastering page, any more than CbB competes with Vegas because CbB has a video player screen. And for DJ mix-type stuff, SO's mastering page isn't anywhere near as flexible as doing album assembly in CbB (nor is Wavelab's "multitrack" Montage feature). Right tool for the right job...

Where it really makes a difference is when you're assembling an album that goes beyond the whole Red Book "individual cuts with two seconds between cuts" protocol.
 

As far as I know Red Book only requires 2 seconds to the beginning of the first track marker.
All others above the first can be anywhere from zero to whatever.
At least that's how CD Architect works.

The only required pregap is indeed 2 seconds before Index 01, although it's also possible "hide" a track between 0 and index 01 (but people have to know it's there - you need to hit play, then rewind immediately, and not all CD drives can read this).
 
However, consumer burning software defaults to two seconds between tracks because that's recommended, albeit not required. They can't change this because you can't place your own PQ codes, as you can with professional CD creation programs like Wavelab, Sound Forge, Studio One, etc.
