You have a difficult yet wonderful choice chooing between these two routes. They’re both great experiences. In 2018 my wife and I walked the Inglés during a very rainy Semana Santa. In spite of the weather, we thoroughly enjoyed the relative quietness of this Camino and the fact thst we were primarily surrounded by Spanish pilgrims. As it was a holiday week, we booked accommodations ahead. This worked out very well as we weren’t sure about how busy it would be since there were fewer albergues available to pilgrims. Although some mornings it seemed as though we had to walk further before our first coffee break, the infrastructure was certainly sufficient for an enjoyable Camino. Several charming towns are found along This Way. In particular, Pontedueme and Betanzos. In Betanzos you have to treat yourself to an omelette or tortilla español that they are known for. I highly recommend Casa Miranda.
Doing the last part of the Portugués, you could start in either Tui or Vigo, is also a great choice. Having walked both routes, including the VE just this past spring, they’re both excellent Camino experiences. Regardless of where you start, walking the Variante Espiritual will be very special. Although you will find more pilgrims on the Portugués route, there are not that many who choose to walk the VE. After the wonderfully historic Pontevedra, there’s a good climb out of Combarro taking you to the Monestario de Armenteira (another special spot). Depending in the time of year, you can reserve rooms there for just a single night. A pilgrims mass and dinner at the cafe/bar just across the street top off a great day on the Camino. In Vilanova de Arousa you can catch the boat for the ride to to Padrón. We traveled with A Mare for a wonderful rude up the river. Between the hiking and this boat section, I look forward to retracing my steps on the Variante Espiritual.
Both are great Caminos. But, if I had to pick just one to walk, I would probably do the Portugués again. Both certainly have pluses and minuses, but overall, the Portugués gets my vote particularly when you include the VE along The Way.
