It is always a very personal opinion.
As always it stands with a very good (technical) restoration.
And a SET like this in a good setup in the room (the advantage is
the separate speakers, which is only logic of course).
Succes.

If it comes to a (large) table model (kind of cliché) :

This may sound somewhat blunt, Mr. *****
But answering your question is rather complicated. There is no such definition as "the best set" neither for Philips nor for any other make.
It all depends upon the personal wishes and expectations of the user. Anyway, you did not mention from what era the set should be; do you wish a really vintage one or from the end of the sixties?
Hoping you understand what I mean

Philips Holland was the originator and pioneer of valve radio sets in Europe from the beginning.

One of the very best radio sets from the beginning of the Philips radio production is the Philips 2511. It is exceptional well constructed and features a cascade of 2 h.f. amplifiers plus AVC. The masterpiece of this set is the 3-fold precision tuning capacitor, in combination with three high-quality h.f. coils. This construction delivers not only a high sensitivity, but also an optimal selectivity.

Such a set is not lightweight, it weights 22 kg without the loudspreker.

This set was sold all over the world, and was an immediate succes. It was the start of the international expansion of the Philips brand. More then 120.000 sets were produced. The Philips 2511 was introduced in 1928.

There is not an easy answer.

You mention "Pionier" versions.

So take a period of construction and look at models and their exclusif construction.
Is that a revolutionairy design?
That in relation to other makers in that period?

The mentioned 2511 is in relation to that models of that year the best buy.
The mentioned B6X62A(1957){pre. is the BX642A-1955] is just a rebuild BX653A (1955) only the idea of seperate loudspreakers instead of build in.
And compair that with fi. a Grundig 9060W(1955) with its 6 speaker design of 12W power output.

Then mark that there where better radio's but fi. a very cheap radio
could also be a best performer for its construction.
That is also an achievment.

Build the best radio with just a few components.

Also the radio with the most amount of "special effects" isn't nessesairy the best performer.

So define your search.
Best circuit design, most revolutionairy design, tube construction, best reception, best quality sound, mechanical innovation (fi. the Monoknop out of 1935 Phlips series).
etc.
Then you want just the consumer marcet??
That according to the date of construction in relation to other designers.
