Mizutani: If XX were still playing... LOL
2023 alone is too small a data point to project how Matsushima will fare in senior events, given that Shinozuka, Togami and Uda had good win rates in 2022 (76.92%), 2021 (76.92%) and 2020 (15/20=75%), respectively. When given the chance, Uda has converted his potential into results by reaching the SF at Singapore Smash 2022 (3-2 Boll and 2-4 FZD) and finishing 4th at Asian Cup 2022.
In terms of All-Japan TTC, Uda is arguably more impressive than Matsushima, even after accounting for the age difference. Both never won the JB event but had reached the final. Uda has won the MS and MD events. The best Matsushima has done is MS R16 and R32 in 2022 and 2023 and MD F in 2023. Yes, he just turned 16 this April, but his opposition is also not as strong.
But yeah, it's better to have Matsushima as another option.
