Colón Vs. Solís, Gaboto, Magallanes, Etc. - Place Names

[yd_mtl]

Excluding street names, why are there many more place names in Argentina with the name of Colón (after Christopher Columbus) than Gaboto (after Sebastian Cabot)* or Magallanes (after Ferdinand Magellan)**, even though both Cabot and Magellan (but not Columbus) explored various parts of present-day Argentine territory in the Age of Discovery? Does it have to do with the pan-Hispanic symbolism of Columbus throughout Latin America as well as Spain? In the case of Magellan, is it because he spent much more time in Patagonia and Tierra del Fuego than in the Rio de la Plata area?

*The only Gaboto I could think of in Argentina is [Puerto] Gaboto in Santa Fé province.
**There are plenty of place names and other things in far southern Chile, though, named Magallanes.

Also, why does only Uruguay (but not also Argentina) have places and sites (again, excluding street names) named after Juan Díaz de Solís - because Solís, during his expedition, landed on the Uruguayan side of the Rio de la Plata but not on the Argentine side?

Moreover, yet again not including street names, why are there hardly any place names or sites in Buenos Aires (city or province) named after Pedro de Mendoza, the founder of the first iteration of Buenos Aires in 1536 - because his Buenos Aires failed against Indian attacks?

Probably it is because the fact that the decision makers, politicians or burocrats around 100 years ago or more, when the towns and cities were created, decided Colón and Pedro de Mendoza as the names. Similar with General Roca and the Campaña del Desierto.

There are gaboto streets in lots of Argentine cities. There is a Solís street downtown parallel to 9 d julio

I grant that there are Gaboto and Solís streets in many Argentine cities. It's just that in Argentina, there are a few towns named Colón and there's also the Teatro Colón right in the heart of Buenos Aires, but only one little town named Gaboto (Puerto Gaboto in full) but otherwise no towns or theatres or the like that are named Gaboto/Caboto or Solís. It seems to be only in Uruguay that there are towns (and a prominent theatre in Montevideo) called Solís - but none by the name of Gaboto or Caboto (there is a Teatro Caboto in Milan, Italy, though); even in Uruguay, Colón greatly outstrips Gaboto/Caboto in terms of town or neighbourhood names, and only Solís is a serious rival to Colón in that respect.
